2011-2019 Challenger Corsa PowerCore Closed Box Cold Air Intake 5.7L HEMI Review & Install

Hey guys. Adam here with americanmuscle.com. Today we’re taking a closer look at and of
course installing the Corsa PowerCore Closed Box Cold Air Intake, available for the 2011
and newer 5.7 HEMI equipped Challengers. Check this out if you’re looking to ditch
your factory airbox for a cold air intake from the aftermarket world that is more on
the premium side of the spectrum. This particular option boasts a big horsepower
and torque gain over your factory airbox, as well as a better throttle response and
acceleration, as well as just making your engine breath a whole lot better. You’re switching out from that factory flat
paper element filter to an extremely unique aftermarket option. This is a very uniquely shaped, uniquely built
custom air filter. It’s a dry filter. Therefore, it does not require as much maintenance
as an oiled option and it’s gonna do a lot better for long-lasting life. This actually, as a matter of fact, lasts
up to 150,000 miles as Corsa lets us know. This is a Donaldson PowerCore G2 Ultra-Web
Nanofiber Filter Technology. It’s got uniquely shaped channels to make
sure it’s maximizing airflow as well as trapping all of the dirt, dust and air particles that
you don’t want making its way into the engine bay, robbing you of some power, all gonna
get trapped up in this unique shaped air filter. The big thing about this particular option
is it’s no maintenance required. You do not need to pop this off every thousand
miles or so to clean it, throw it back in, re-oil it, none of that nonsense. You leave it on, forget about it and it does
the job nicely. The other thing that’s nice about the Corsa
option is its closed box technology. This is gonna do one of the best jobs in the
category, keeping out your engine bay heat and pulling in all of that cold air. It’s got new polyethylene construction with
a nice textured black finish, so it looks really good under the hood, and it’s got a
really subtle Corsa Performance plate right on the front here too. That’s really blending in, it looks really
stealthy, and it just honestly looks really good. There is no easy access to the filter, I will
say. But then again, with no maintenance required,
you don’t really need it. Looking at the inside here, you can see that
it really does close in that filter, comes with an extension tubing that’s preassembled
on our box. It’s got the same polyethylene construction
for the tubing and elbow going into your throttle body, and I will say that these are going
to be a lot smoother than your factory tubing. There’s gonna be a whole lot less, if any
turbulence with the air flow coming in, which again can rob you of that power. Power, speaking of which, Corsa lets us know
you can expect up to 18 horsepower and up to 23 foot-pounds of torque with this installed,
and those are curve gains that I would expect at the low end, making it a lot more driveable
and a lot more fun on the road. Low end torque like that added with a simple
cold air intake that doesn’t even require a tune does a whole lot for drivability. If you wanted to pick this particular kit
up with the very unique air filter, the very unique dry filter at that, you can do so for
right around 330 bucks. And the install’s gonna get two out of three
wrenches on our difficulty meter. Anybody can tackle this on the driveway at
home, and the fact that some of it comes preassembled right out of the box just speaks wonders to
how easy this is gonna be. Anybody can do it with simple hand tools in
about an hour, maybe two at the absolute most depending on your experience. But again, anybody can tackle it. This is one of the easiest things you can
do under the hood for your 5.7. Tools used in this install include an impact
gun, quarter inch and 3/8 ratchets, extension, 7, 8, 10, 12, and 16-millimeter deep sockets,
15-millimeter wrench, flathead screwdriver, and a panel removal tool. All right. Step number one for the uninstall, of course,
just pop off your engine cover. Now of course, we’re working with a 5.7. This may be a little bit different for the
guys out there with a 6.1, but shouldn’t vary too much. Just pop off that engine cover and just set
it aside. Next up, we’re gonna do our sensor right on
the side of the tubing that connects to the throttle body. It’s really just a pinch and disconnect. From there, you actually wanna remove the
fitting for the sensor itself which you’re just gonna twist and pull straight back on. This is extremely sensitive so set this aside
and just make sure it’s out of the way of any danger. Next up here, grab an 8-millimeter socket
or a flathead screwdriver and we’re just gonna loosen up the clamp holding the intake tubing
to the throttle body. From there, you should be able to just twist
it up, pull this back. Before we can remove this, we have one more
bolt to remove as well as a hose, and then the whole thing will come off in one piece. All right. Next step is the bolt holding the factory
heat shield to the front support. That’s also an 8-millimeter. Just loosen that up and take that out. From here, we’re gonna disconnect the hose,
the breather line on this end, just gonna wiggle it back and forth and pull it straight
back. At this point, we should be able to disconnect
this from the throttle body and pull it all up in one piece. All right. This we’ll pull straight up, pull out of the
throttle body. Can lift up on this end here, and we’re just
going to set all this aside. Now, this bracket was used to hold on that
factory intake at the extension portion, so we’re just gonna go ahead and remove it because
we’re not gonna need it for our aftermarket intake. So, I’m gonna take a 16-millimeter socket
and just remove this bolt. At this point, you can grab a 15-millimeter
wrench to hold the inside bolt, grab your 16 socket again, and just pop off the nut
on the outside. She can be a little rusty. This way, the bracket’s out of the way, but
there isn’t an open hole there. Just thread the bolt back in there and
tighten up that nut. I wanted to take a second to talk about the
differences between our Corsa option and our factory intake from our 5.7. Now there is a huge difference in almost every
single aspect of the kit when comparing it to the factory intake, and the biggest one
is gonna be the filter and the airbox. Now the airbox itself is where I want to start. This injection molded material does have the
Corsa name on the side, which I think is a little bit cooler than the factory intake,
it’s a lot neater looking. This is also a lot of a tighter fit in the
engine bay. It’s gonna do a better job of completely and
utterly sealing in our ultra nanoweb paper element filter here, whereas the factory one
does leave a little bit open. It’s not the best in pulling in as much cold
air as possible as it is pushing out all of the hot engine bay heat. This one also has the extension tube going
all the way down. Now that is somewhat similar to our factory
airbox that has this inlet at the bottom. This Corsa option takes it a little bit further
though and has this duct that goes straight down where this would connect and goes a little
bit farther to our lower grille. That means it’s gonna pull in a little bit
more cold air and it directs it straight into the filter, ultimately into the throttle body
and the intake manifold. So this does a lot better than this. It honestly just takes the same technology
and moves it forward a little bit more. It’s also got a slight difference in the tubing. The tubing isn’t gonna be kinked up like our
factory one. This causes a lot of air turbulence, doesn’t
really streamline the pull of cold air as much as the Corsa one would. So you should see a little bit of a power
bump there, simply off of the streamlined air flow. Now, as far as a little bit of a smaller note
here, our couplers are a little bit more high-end. This is already built into the factory intake. This has a little bit more of a blue finish. Not something you can really see when it’s
installed. You might see a little bit of the edging,
but as far as the quality of the couplers, I think this is a little bit better than everything
the factory uses to connect to your throttle body. Overall, the filter is a paper element just
like your factory one. It’s got a very unique shape as far as the
dry paper elements go. It’s gonna be the same quality of materials
that your factory one uses. It’s just built in a way that is made to filter
out better while also pulling in more cold air. It’s a very optimized paper element filter
as compared to your flat paper element in the factory airbox. With all of that said, guys, I want show you
how it gets installed. So, what do you say we get started? The first step here is to take your PowerCore
filter and insert that into the closed airbox. You want to make sure you’re orienting the
clamp properly so that you can access it through this little cutout here. This is where you’re gonna stick your extension
and your socket or your flathead to tighten it down. So, just make sure that clamp is accessible
through this slot. So, I’m gonna go ahead and insert that filter
now. You wanna have it about in that top left section. Look through that hole to make sure it’s aligned
properly. Now, I have a small extension with an 8-millimeter
socket. You can also use the flathead, put that inside
and tighten it down. Next step, grab your 10-millimeter bolt, lock
washer and flat washer along with the supplied bracket, that’s gonna install onto this pre-drilled
and threaded hole on the side of your intake box. So, we’re gonna set that into place with the
elongated portion down, we’re just gonna tighten that down by hand, just start threading that
down. Now, it may need to be adjusted later on. We’re gonna tighten it about in the center
just to have a neutral starting point. The next step is to take your airbox and flip
it upside down with the Corsa logo facing downward to access this part here. Grab one of the straight flat sleeves and
insert that over top of that with one of the provided clamps. You want to make sure you’re using one of
the smaller clamps that’ll fit over properly. Get that into place, grab that 8-mil socket
or your flathead and tighten down your clamp. First up here under the hood is to grab the
weatherstripping included in the kit, take the aligned metal portion of that weatherstripping
and line it straight across your frame here. From here, we can grab our airbox and drop
it into place. At this point, grab your new Corsa box, drop
that into place. Now, you want to be careful of the ABS lines
down there of course, and drop it in. You wanna make sure this bracket aligns properly
with the retainer bolt that’s still there, that U-nut clip from the factory. If you need to just the positioning of the
bracket, just pull that out, adjust it, but ours is looking good. Now, we can bolt it down. Reuse that factory 8-millimeter bolt to tighten
this down. Now, take the supplied coupler that’s gonna
attach your air duct tubing to the elbow going into the throttle body. Make sure you have two of the appropriate
sized clamps set over the coupler before you put this into place. Once you have it inserted to the middle here,
grab your socket and tighten down the one attaching it to the airbox tubing. The next step is to install our elbow attaching
this tubing to the throttle body. But before we can do that, we have to install
the coupler that’s gonna attach the elbow to the throttle body itself. Now, take that coupler, put one of the appropriate
sized clamps on one end, same on the other. I like to have both of the clamps facing the
same way, it just looks a lot cleaner under the hood. Install that on the end here with your mass
air flow sensor mount, grab your socket and just gonna tighten this one down to hold it
together. From here, insert the elbow into the tubing
as well as the throttle body. And you may need to make adjustments to the
tubing coupler just to extend that a little bit more to have them connect. Next up, grab your MAF sensor and carefully
twist it into position on the rubber grommet. Once you have that seated all the way, make
sure it’s facing the throttle body and connect your sensor harness. Next step, remove the entire factory breather
hose. Just pull that straight off and set it aside. Replace it with the one provided for you by
Corsa. Set that all the way on your new fitting,
and then back in the factory location, just seat that all the way back. It’ll hold itself in place. Well guys, at this portion of the install
you’re pretty much complete under the hood. This is all completely installed. You can start your car once your MAF sensor’s
plugged in and get going. The next portion of the install is for the
guys who really wanna take full advantage of everything the Corsa intake has to offer. Corsa’s including an extra Corsa scoop, that
they call it, which is gonna translate to a little bit more power, better throttle response,
and overall just more air making its way to your intake manifold. Next in order to do that, I’m actually gonna
put our car in the air on our lift. We’re gonna have to remove our skid plate
to gain access to a panel by the fog lights. It’s a little bit more involved than a regular
cold air intake, but that’s how you take full advantage of what Corsa has to offer. If you’re working on the ground in the driveway,
you wanna make sure your car is supported on jack stands. Get it up in the air, able to remove the entire
skid plate from underneath the engine. First step we’re gonna do, put it up in the
air and I’ll show you guys how that works. Guys, the first step, we got this up in the
air, is to grab a panel removal tool and we’re gonna remove a couple of plastic pushpin rivets
that are all along the inside and edges of your skid plate. In order to do that, I recommend the panel
removal tool, but of course using a flathead screwdriver could work as well. This just makes life a little bit easier. So there’s there right here in the front. There’s three or four along the inside of
the wheel well lining the bottom and sides of the skid plate. And then, we’re gonna remove several 8-millimeter
bolts along the front. There’s a few 10s located around the sides
and in the middle here as well. And then, the whole thing will come off together. There’s just three in this wheel well that
I’m popping out now, doing the exact same thing, just pry these out of position. They come off together. I’m just gonna set those aside on the floor
here. Same thing on the side over this way. All right. Now, we’ve got my socket on the end of the
impact. This makes life a lot easier. We’re going to go straight across the bottom
of our chin splitter to remove all those tiny screws that are holding it on from the front. Now, I can switch over to a 10-millimeter
and remove the two on the back, and there’s two in the middle as well. All right. At this point, our skid plate’s starting to
disconnect. Just wanna make sure that you’re there to
grab it. The next step is to remove this panel right
next to the right of your driver side fog light. So, this has to come off. You can see it’s being held on with a wire
and a Christmas tree clip, and the same thing at the top. Gonna pop that off, pop the top one off and
remove that panel. The next step is to take this retainer stud
and screw it onto the stud you see here to the upper right of the fog light. I’ll show you what this is gonna do in just
a moment. We’re just gonna thread that on that stud. Just screw that all the way up, and you can
see it now has threading on the bottom of that. That’s gonna allow us to bolt that extension
bracket that’s twisted on the end to that, which is gonna retain the Corsa scoop. Now, the flat portion here, you want to install,
now I know it’s gonna be tough to see for a moment, but once I’m out of the way you’ll
be able to get a good idea of what’s going on. We’re gonna use the 10-millimeter bolt included
in the kit to tighten this down. As you see, we installed that bracket to the
retainer that we put onto that factory stud with a 10-millimeter bolt on the inside. That’s gonna hold it right in place. Now, we’re gonna bolt it up straight just
like this, and if we need to make adjustments, we will. This is gonna bolt up to the Corsa scoop. Guys, at this point, you’re not gonna be able
to see what I’m doing up here. It’s an extremely tight space. But, what we’re gonna do is install that Corsa
scoop just like this up into the coupler. We now have access to the bottom of that airbox. And if you remember on the table, we installed
a rubber coupler to the bottom of that, which is now coming through here. That’s gonna tighten to this, and this open
end is gonna be facing the now open lower grille. That black panel we just removed from that
spot was blocking off the air flow, but now that that’s free, this is basically just gonna
be an open inlet to pull air straight into the cold air intake box that we have now from
Corsa. So, I’m gonna install this up to the coupler
with this facing forward with a clamp over that coupler. I’m gonna tighten that down with a ratchet
since it’s a really tight spot. The opposite end has a threaded hole. That’s gonna bolt up to that bracket we just
installed. That’s gonna keep it solid in position and
not able to move. So first thing’s first. I’m gonna set my ratchet aside, set this clamp
over the coupler. Now, you may have to just shuffle out of the
way the splash shield, the fender well, the fender liner to have that coupler set in place. Once that’s up there, I’m gonna insert the
scoop. Now, just rotate so it lines up with that
bracket. I’m gonna grab my ratchet and tighten down
that clamp. At this point, we can take another 10-millimeter
bolt from the kit and tighten that bracket to the side of the tubing here. And then, we can grab our socket and tighten
that bolt down. So guys, we’ve already got everything installed. The last step of the process is to just reinstall
our skid plate. We’re gonna take care of that, put the Challenger
back on the ground, and then throw, of course, your engine cover back on top, and you’re
good to go. All right. Last step being that engine cover. We’re just gonna pop that into place. Well guys, that’s gonna wrap up my review
and install for the Corsa Performance Closed Box PowerCore Cold Air Intake available for
the ’11 and newer 5.7 HEMI equipped Challengers. You can get your set right here at americanmuscle.com.
