      Noah: Hey, it's Noah from AmericanMuscle. And what I have here in front of me is the Corsa Performance Closed Box Cold Air Intake with the MaxFlow 5 Oiled Filter for the 2018 and newer Mustang GT. Now this intake is the perfect choice for an S550 owner who's looking for an aftermarket intake that offers some serious performance gains without requiring a tune.The main goal with the cold air intake is deleting the restrictions factory intake tubes come with. So Corsa's intake tube is restriction-free, which is gonna increase throttle response as well as horsepower and torque. So without any restrictions, silencers, or baffles, air is free to move into your engine faster. And we are looking at an 18% flow increase over the stock intake, as well as an increase of 20 horsepower and 11 foot-pounds of torque.Now the blue MaxFlow 5 Filter comes pre-oiled. So right outta the box, you're protected from smaller particulates floating around the engine bay for 40,000 miles. And then this filter is also reusable. So when you hit that 40,000-mile mark, or when this guy gets dirty, you can just clean it and re-oil it rather than buying a whole new filter. Then lastly, that filter sits inside a fully enclosed air box with a clear top. Now that way you can see when that filter is dirty without taking the whole thing apart.The intake is constructed from black heat-resistant plastic. That means this intake is lightweight and it's cheaper to buy than something constructed out of metal, but still sturdy enough to resist cracking or warping because of engine bay heat. And plastic is also known to dissipate heat faster than metal. So this should help keep those intake air temperatures down. And the air box has been rotomolded and designed to keep heat away from the filter, and hand in hand, it'll keep dirt from hitting the filter as well. Then to top it all off, this guy comes with a one-year warranty to protect you from any manufacturing defects.So let's talk price. Corsa's cold air intake comes in right around the $450 mark. This intake is near the top of the price range when it comes to aftermarket intakes for the S550. Now Corsa really has made a name for themselves, and they make fantastic products. So the price may be higher than some other options, but you know you're getting something that is quality and well-designed.This install is gonna fall at two out of three wrenches of difficulty, and the job is gonna take you about two hours to complete. It is going to require some light mechanical skill. However, all the parts you need to get the install done are included with the kit, like all the clamps and fittings. Without further ado, let's head over to the shop and get this on our S550.Man: The tools you'll need for this project are a ratchet, a 7-millimeter, an 8-millimeter, a short 10-millimeter, a deep well 10-millimeter, and a short extension, a 9/16, a 13/16 wrench, a T20 Torx bit driver, a flathead screwdriver, a number 2 Phillips screwdriver, a pair of pliers, and a trim removal tool. Hi, everyone. Today we're installing a cold air intake on our Mustang, but first, let's watch a short video on how to uninstall the stock intake first.Woman: Okay, so the first step in our install once the hood is popped is to grab a trim panel removal tool and remove two covers on each side of the engine cover to expose some nuts that we have to remove. Okay, so you will see two little cutouts on either side of this cover. Just take the end of your tool and pry up in one of the cutouts, and this should come out. Repeat that process on the other side. So there are two 10-millimeter nuts, one in each side of the cover. You're gonna want a 10-millimeter socket if you can find one and a nice long extension to make sure you can get on the nut. Go ahead and loosen it up and remove it. Repeat that on the other side. Okay, now that these nuts are removed, you can grab your cover on the edges and pull it off. There should be several clips that you just need to release in order to remove the cover.Okay, now I can disconnect the MAF harness. Pull back on the red tab. It might be hard to see, but it's on the bottom here, press down, and release. Now you can release this vacuum line on your intake tube, press down and release it. Next up, we're gonna remove this crank case vent line. There's a blue tab, press back on the blue tab and it should come free. Just press backwards on this blue tab here to release those. Okay, now you can grab a set of pliers and release the sound tube. Go ahead and squeeze the clamp, and you should be able to wiggle the tube off.Now if you can't get it off by hand, you can gently pry back on the tube with a flathead. Just be careful not to damage the rubber. Next up, grab your flathead screwdriver and loosen up the clamp holding on your tube to your throttle body. Go ahead and wiggle it to remove it. All right. Grab your 10-millimeter socket again and go ahead and remove the bolt holding on the air box.All right. Now we do have to remove this one pop clip that holds the MAF sensor connector line onto the air box. So go ahead and grab a pop clip removal tool. Go ahead and pull that off. This back part of the sound tube is also connected to the air box, just grab and pull it up and out of the way. Now that everything is disconnected from the air box, we can grab it and lift it out and off of the car.Man: Before we can install our new intake on the system, we've got a couple of things that we need to take care of. One, we need to transfer our mass airflow sensor here to the new inlet tube, and we need to remove this grommet in the corner for the hold-down of the new air box. So to do that, we're gonna need our T20 Torx bit to remove the two screws here on the mass airflow sensor. Once you've got the screws removed, the mass airflow sensor just slides out. Now we can remove this metal bushing out of the rubber grommet for the hold-down and then just compress the rubber bushing to pop it out.Now the kit does also come with a new rubber seal for the mass airflow sensor, and it only goes on one way. The holes will line up perfectly when you've got it installed properly. So now we can just do that and transfer it over to our sensor, slide it in, and use the supplied screws with our number 2 Phillips screwdriver, and put them in. Now we'll install the new seal on the mass airflow sensor, slide it into place, and use the supplied screws to secure it to the tube.All right. Now we can move on to installing the rubber grommet on the new box. Now we'll install our rubber grommet and our metal bushing into the corner of this air box right here so that we can secure it to the vehicle once we get it installed. Now to install this rubber grommet, you'll notice that there's a rounded edge and a flat edge. The rounded edge is gonna go through the box towards the bottom and you just work it around until it all goes in. Now, if you're having a little trouble getting it all the way through, you can use a flathead screwdriver on the bottom and just kind of help work it through so that it's completely secured to the bottom of the box. Now, once you've got that in, you can go ahead and install the metal grommet through the center.All right. Now that we've got our rubber grommet in, we can go ahead and install this rubber seal around this opening here where the air filter sits to make sure that we've got a good tight seal. Now to do this, we've got one side that's open, so we're just gonna push that in. I like to start at the bottom, just because it looks neater, and just work your way around, pushing it up so that it secures it onto the box. There we go.All right. Now we can go ahead and install our two plastic fittings for our hoses. And you're gonna want to use... You'll notice that there are two different sizes on the ends here. You want to put the larger of the two fittings on the inside of the bend here, and the smaller goes underneath. So we'll go ahead and screw these in. Now you do want to take care not to force this because they are plastic and they are soft, and if you try and force it, you can strip the threads out. So then we'll put the smaller one in at the bottom here. Now you can tighten these down, but you don't want to over-tighten them. Just tighten them down till they stop. The smaller fitting is going to use a 9/16 wrench, and the larger one will use a 13/16 wrench. Like I said, just tighten them down till they stop.All right. Now that we're ready to install our air box, we need to go ahead and remove the sound tube that was connected to the old one first. To do that, we're gonna use our trim removal tool and we're gonna get right underneath this push pin on the shock tower here, pop that out, and then there's a 10-millimeter nut that we can't actually show you on the firewall because we just can't get the camera in there, but you'll be able to see it once you get started on it. So let's go ahead and pop this out. We'll just slip this underneath this push pin, pry it up, and then we can remove our factory sound tube.Now with the factory sound tube gone, the kit does supply you with a new plug to go in that firewall where the sound tube used to be. Now, like I said before when we were moving the sound tube, the camera angle, we just can't get in there, but you'll be able to see it when you're working on it. So we'll just go ahead and pop this in and that'll cover up the hole. So here's our tube and it's right back here on the firewall. And you just kind of have to feel your way around as to how to get this to seat into place. And there you go.All right. Now we're ready to install our new box. And you wanna make sure when you slip this in that this goes into the factory fitting next to the radiator here so that you get good airflow coming in. And once you've got that in place... All right. Now we can go ahead and reinstall our original bolt that we took out into the grommet that we inserted, that we transferred from the old box. It's a little bit of a tight fit because it is right in the corner here. Once you get it started, you can go ahead and use your 10-millimeter socket and your ratchet and get that secured in place. Now we'll go ahead and install our air filter. And again, it is tight clearances in here, so you may have to work it around a little bit to get that pushed through.Now we can install our inlet tube. Now we'll use the smaller of our three hose clamps and put it on the small end of the coupler and put the coupler on the throttle body. Just make sure that that's seated all the way on the throttle body, and the hose clamp you have access to in order to be able to tighten it. Now we'll go ahead and put our larger clamp around the air filter, and then we can put our medium size clamp over the end of our inlet tube. And we'll go ahead and put the tube into the coupler, and then the other end into the air filter. Now once we've got those all hooked up, we can go ahead and tighten down our clamps using our 8-millimeter socket. All right. So we'll go ahead and use our 8-millimeter socket and tighten up these clamps. Now we can go ahead and hook up our hoses in the original locations. Now, with our clamps all tightened down, we can go ahead and reconnect our hoses and our mass airflow sensor.Now we can go ahead and install the top to our air box, making sure, of course, that the rubber seal goes towards the box. And we wanna make sure that the rubber washer is on the bottom of the screw. Go ahead and get those started, and then use your number 2 Phillips screwdriver to tighten them down. And again, you don't wanna get crazy with these. Just make sure that they're snug and tight.And finally, we can reinstall our engine cover. Put that back in place. Now because this pocket here is so deep, it's a little tough to get your fingers in there. So one of the things I like to do is just put the nut into your socket and then use a little piece of tape just to hold it in place while we put it in. Then when you set it down on top of the stud, give it a few quick turns and it's locked into the stud. Now you can go ahead and secure that, and we're done.And that wraps up our review and install of the Corsa Performance Closed Box Cold Air Intake with MaxFlow 5 Oiled Filter for the '18 to '23 Mustang GT. Thanks for watching. And remember, for all things Mustang, keep it right here at
