      Video Review & Installation

      Hey, guys, Stephanie with here with my overview of the Roush Cold Air Intake Kit, available for the 2015 and up EcoBoost Mustang. This overview is gonna cover a few topics with the Roush kit, like what you can expect from this intake, some info about the components and the construction, and some info about the install. The install for this is a simple one. It's a one out of three wrenches on the scale, but I'll get more into that a little later on.Now, cold air Intake is normally one of the first mods that many Mustang owners go to. But there are a ton of different choices out there between airbox styles and filters. And the Roush intake is one of the options that are available right now that bring some of the most benefits to the table.The factory intake is actually really good. It's highly functional, and it isn't as restrictive as you might think it is. But aftermarket cold air intakes like this one function a little bit better than the factory intake in the upper RPMs and especially after some mods have been completed. The Roush does have an open airbox design. But the fact that it keeps the direct cold air feed that Ford created, where cold air from outside the car enters through the grille and feeds the air filter, means that this is one of the more true cold air intake setups, since it does receive some air from outside the engine bed.Like other aftermarket intakes for the EcoBoost, this one does not require a tune. No aftermarket intake for the EcoBoost requires a tune, because these cars are speed-density cars. Now, the requirement of a tune with aftermarket intakes comes from the size of the MAF or the mass airflow. And aftermarket intake can only go so big with the MAF size before the car's gonna need a computer tune. Now, even though this is the case with EcoBoost, I do wanna be clear with the fact that you're only going to see gains of a few horsepower without a tune. So you can expect a small bump in horsepower and torque along with improved throttle response overall.But let's look a little bit more at the intake itself. The first thing I noticed was that the filter's actually pretty large, and it's bigger than the other filters that are out there on other cold air aftermarket intakes that I've seen. This is a reusable, high-flow, dry-air filter, which is nice, because when it gets dirty, you can clean it and reinstall it and not have to worry about the oiling process. The intake also fits really nicely. And I think it looks better under the hood than the stock airbox does, for sure.Now, another cool thing here and one of the big things that I wanted to point out with this intake is the airbox. This is important, because the airbox does still keep that air feed from the grille, which, I mentioned earlier, it actually brings in air from outside of the car. Not all aftermarket intakes do this. And I like that they've tacked into that factory cold air duct, because it gives performance gains and allows for more of a true cold air setup.Looking at the price for this Intake, you can expect to pay close to the $400 mark. Now, this is on the more expensive side. But you are looking at a different housing, a larger filter, and the foam insert and the hood seal to keep the intake isolated.As for the install, it's nothing too difficult. And like I mentioned earlier, the intake will come with all of the items that you need to complete the install. All that you really need then to complete the install is a few basic hand tools. This is probably one of the easiest mods that you can tackle with your new Mustang, and it'll take about a half hour or an hour, tops. And I'm going to call it a one out of three wrenches on our scale.All that you really need to do is remove the factory airbox. You need to disconnect the airbox from the inner fender and remove the inlet tube from the air filter and the throttle body. We're just talking about a few bolts and clamps to get this done. The Roush installs the same way as the factory airbox came out. Just put on your new couplers and clamps and slide the airbox in, starting with the air duct first. And that just goes right into the factory location. Once you have everything installed and lined up properly, you can tighten it all down, and you'll be good to go. Wrapping things up here, this intake from Roush is a good-quality option that fits and looks great and gives some performance and sound gains, has a large, reusable air filter, and the housing taps into the factory cold air duct.
