    Video Review & Installation

    Justin: Roush Cold Air Intake that we have here will be one of the most popular options currently on the site for your 2005 to 2009 3-valve GT and we'll land right around the $300 price point. Now, this intake will include the roto-molded plastic intake tube and airbox along with a high flow oiled filter, along with the very unique feature that allows this intake to be run either with or without a custom tune. And that, of course, is this removable mask airflow insert. Now the install itself will require zero modification whatsoever. It will be a very easy day in the garage. So, let's go with one out of three wrenches on the old difficulty meter, but be sure to hang out towards the end of this video and we'll show you how to get it installed.So, Roush is obviously synonymous with Mustang performance and parts so it's really no surprise that there are three valve cold air here is again, one of the most popular in that premium tier. Basically, intakes, they're gonna land above that $300 price point. Now, some of the big draws with going with any aftermarket cold air would, of course, be that underhood appearance upgrade, all with a little bit more sound in a little bit more power coming from that 3-valve engine. But again, one of the most unique features here with the Roush cold air intake is the removable mass air flow insert, allowing this intake to be run either with or without a custom tune of your choosing. Now, we'll leave that insert in, and again, you can run the Roush without a custom tune, basically pick up gains of high single digits to low double-digit horsepower and torque for most owners out there without again, using that custom tune. However, yank out that insert, upload your favorite custom tune, and the gains will only increase from there.Now, aside from the power upgrade or power gain, you can also look forward to things like the noticeable increase in sound or brow coming from under the hood, which is certainly something, a number of our customers have pointed out in the review section. So, as always feel free to read up on those if you haven't already done so. As far as your construction is concerned well, Roush typically nails their build and fitment, and the same can be said here with their particular cold air. You're looking at roto-molded plastic for the intake tube itself, along with the air box, which does, by the way, seal to the underside of the hood with the included weatherstripping. And that's gonna help prevent any of that hot engine bay air from entering the high flow oiled filter. By now, guys, you should know that these guys are washable. They are reusable. Just clean them up, reoil them as needed, and it will certainly help save you some money in the long run as opposed to replacing those factory panel style filters every year or so.Now, I do wanna point out that the Roush is currently not CARB certified. So, 3-valve owners out there in states like California, for instance, will need to entertain a different cold air option. But, now let's tackle that install as promised earlier, and again, expect a very easy day in the garage or driveway. And to give you a better idea of what's involved, here is Tony with a detailed walkthrough, along with a quick tool breakdown.Tony: All right, thanks, Justin. Now let's go ahead and get started with the installation of our new Roush cold air intake. To do that, we have to remove our factory intake tube and airbox from the vehicle. Now to do that, we're gonna loosen up our clamps on the throttle body, take out the retaining bolt that locks our airbox down to our inner wheel well. Unhook a few plugs, a couple of airlines, and we're gonna lift our entire intake out as a unit.Tools used for this installation are as follows, a utility knife, a impact gun or ratchet, a few different size Allen keys, a 10-millimeter and an 8-millimeter socket, and a T20 Torx bit. Now let's go ahead and get started. Now we're gonna come in and remove this vent tube here. Now there's a little clip underneath, you push that out, and just slide the tube off. We'll spin that out to the side. After that, we're gonna come over to our mass air flow sensor and unplug that, you're gonna pull back the little red clip, push down, and unclip it. With those two disconnected, we can go ahead and loosen up our clamp. You can use either an 8-millimeter socket or a flat-head screwdriver. I prefer to use a socket. I think they just grip a little better. We'll loosen that up. Give the intake tube a small tug. It should just break free. Now with a 10-millimeter socket, we're gonna remove this bolt that holds it down to our inner wheel well. Now we're gonna go ahead and save that bolt because we're gonna use it for the re-install.All right. Now we're ready to just go ahead and lift our entire intake out as one piece. All right. As you can see here, our factory intake compared toward new Roush intake, our inlet tube on our factory one has a few bellows in it to give you some movement and it has all these ridges in it that kind of slows down the air, creates a lot of turbulence. You're gonna lose a little bit of power there. So, a new Roush one it's a little bit larger, it's more free-flowing. It's gonna make a nice, smooth transition with the air. So you don't get all that turbulence, it's gonna add horsepower. The other big thing is our new free flow filter, that is going to suck in a lot more air than our factory paper style.Now let's go ahead and get this installed. And like I said, we've got to take our mass air flow sensor out of our factory one and put it into our new one. All right, now, with the use of a T20 Torx bit, they actually supply one with the kit, but I'm gonna use my own. Just gonna remove the factory hardware. We're just gonna slide that out. Now we can go ahead and get rid of our factory airbox. Now we're gonna go ahead and slide that sensor into our new air tube. Now on the side of your sensor, you will see a small arrow with the word flow. You wanna make sure that you are pointing that arrow towards your throttle body. Now install the new hardware that comes with the kit. And tighten these down using a 3/32 Allen key.Next, we're gonna put in this rubber grommet that comes with the kit. Now, this is so you can attach your vent air tube back to your new intake tube. That's gonna go in this hole, provided to you from Roush, wanna make sure that it's properly seated because we have to slide in a small metal tube. Next, we're gonna slide in this small metal tube into that grommet. This will be our fitting for our new vent tube. Now let's go ahead and push that into it, you should feel it lock in, and you'll be good to go. Next, we're gonna attach our air filter adapter to our new heat shield/airbox. Now, to do that, you're gonna use three-button head bolts that come with your kit, plus a supplied washers. Now to tighten those down, we're gonna use a 5/32 Allen key. We can go ahead and just line up the three holes, get those snugged down.All right. Next, we're gonna go ahead and get these installed in our car. Now, to do that, we're gonna start with our airbox and get that bolted down into place using the factory bolt and this small aluminum spacer with the supplied washer. After that, we'll get our rubber couplers on and our intake tube. All right. Now, if they came off with your factory box, you're gonna wanna retrieve the two rubber grommets that go down in here. If not just make sure that they're in these holes. After that, we're gonna go ahead, slide our new airbox down into place. All right. Now we are gonna need to remove this 10-millimeter bolt, but we are gonna reuse it. Let's get that out. Now we can set our airbox down into place. Reinstall that 10-millimeter we just removed. Now we're gonna take our aluminum spacer and line it up in our airbox in this large hole with our bolt. We're gonna secure that down where the factory air box bolted down at. And with our 10-millimeter, tighten it down.All right. Now we're ready to go ahead and get our intake tube installed. As you can see, I already put our rubber couplers on our tube with our clamps, but I didn't tighten them down just yet. Once we get it in the car, we'll go ahead and snug them down. After that, we'll get our mass air flow sensor plugged back in, then our vent tube. Slide our coupler over our air filter, and then over our throttle body. Now we can go ahead and get our clamps tightened up. And we're gonna use our same 8-millimeter that we used earlier.All right. Next, we can go ahead and get our mass air flow sensor plugged back in. Now that just plugs in the same way that you unplugged it and make sure you push in that red locking tab. Next, we're gonna get our vent tube plugged back in, but as you can see, it doesn't quite reach. So to solve that problem, Roush gives you a rubber hose to replace the plastic hardline that is on here. To do so, we have to cut our hardline off of our fittings, we're gonna go over to the table and take care of that. And I'm gonna show you how. Now using a sharp utility knife, just go ahead, cut your tube off, making a small slice downside, and pulling the fitting off. Do that for both sides.Now, we're gonna replace that using this rubber hose. Now, I like to go ahead and just slide my fittings back over our factory fittings on our motor and intake. Then I'll take the tube, slide it over one end. It's gonna be a tight fit, but that's exactly what I want. Now we'll just slide over to this end and put the tube on. There we have it. And our intake is complete.Now, hope you enjoyed this video and it showed you just exactly how easy it is to do this intake at home, in your garage, or in your driveway.
