      Review & Installation Video

      Hey, guys. Adam here with Today, I'm bringing you a quick overview and installation of the Roush cold air intake kit fitting all 2015 and newer 3.5-liter EcoBoost F-150s. So in this video, we'll be going over the functionality and benefits you can expect from the Roush cold air intake kit we have here, as well as all the materials and construction since they kind of go hand in hand. Now, I'll top the video off with the installation, which I'll let you know up front here, will be one of the easier mods you can do to your EcoBoost engine so it will get a very easy one out of three wrenches on our difficulty meter.The Roush cold air intake kit will be for any 2015 or newer 3.5-liter EcoBoost F-150 owner who might be looking to swap out their factory air box to pick up an upgrade to give you a better air flow, leading to a better throttle response with something that is a very well-known brand, 50-state legal, while all reaping the benefits without a custom tune. Now, everything you see on the table with me today, as well as all the clamps and hardware that will be included in the kit that you don't see here, will all be a higher-quality material and construction as compared to the factory stock air box. Now, with that said, this is going to be a better ABS plastic with a textured finish. The Roush filter is really the star of the show, however, I'll touch on the materials and construction of that later. But it is worlds better than the factory option and it's washable and reusable, huge plus there. Moving on to the air box itself, this is something that will keep all the dust particles out and the heat out, making sure this is pulling in cold air from the outside, and everything else in between is also gonna be a big upgrade. I'll touch on everything a little bit later, but I do want to point out again that this is something that does not require a tune, or a custom tune I should say, in order to work properly. There's a huge bonus there and a big Roush name is definitely something that a lot of people will be after with the aftermarket world to replace a stock option. Speaking of no tune required, since your 3.5-liter EcoBoost utilizes a speed density meter instead of the mass air flow, it can make changes to its computer on the fly, whereas a mass air flow would require a custom tune. And because you don't require a tune, you don't have to worry about spending a couple hundred bucks or a couple hundred extra bucks on top of this in order to make it work properly. In this case, it's a simple, direct the bolt on and go.Now, the last point I want to make on tuning is if you do want to maximize the potential of the cold air intake, a tune is definitely, definitely a good option, not required, however. That's kind of the point I'm trying to make here. So if you have the couple extra bucks and you really want to maximize the potential, go ahead and pick up a tune, but if not, then it's really not something you have to worry about. You will see performance gains and benefits from this particular option.As far as the actual performance gains, you can expect single-digit numbers as far as horsepower and torque is concerned. What you can really expect is a better engine sound, an overall better air flow coming into the manifold, and most importantly, an improved throttle response, something you might be feeling in the pedal there just to give you that little oomph to get through the line. Now again, not something with crazy, world-changing benefits as far as horsepower and torque, but you can expect single-digit gains at best.So one thing I do want to point out here is that it is 50-state legal so it is great for the 3.5-liter EcoBoost owner out there in California or emissions-restrictive states like that. However, if you have any other engine other than the 2.7 or 3.5 EcoBoost, unfortunately, this kit is not going to be 50-state legal, so keep that in mind moving forward.So again, one of the best thing

      Pick a Power and Difficulty Level. Among auto enthusiasts, the name of Roush is one redolent of high-octane power and performance – a point amply proven by the Roush Performance Cold Air Intake Kit, in this case designed for the 2015-2017 F-150 fitted with a 3.5L EcoBoost engine. Configurable in several different ways, this CAI sucks in enough cold air to generate either +10 horsepower and +8 torque ft-lbs (with an 85mm MAF) or +15 hp and +18 ft-lbs of torque (with a 105mm MAF). This American-made part also boosts throttle response and fuel economy, as well as giving your engine a stronger induction sound.

      Tune Possibly Needed. No tune beyond the factory tune of the ECU (electronic control unit) is required if you decide to install the Roush Performance Cold Air Intake Kit with an 85mm MAF. If, however, you elect to get bigger power gains with a 105mm MAF then you’ll need to retune the engine with aftermarket tune in order to get the intake working properly.

      Tough, Reusable Oil-Free Filter. The Roush Performance Cold Air Intake Kit includes an air filter element that is made out of cotton fabric sandwiched around two nesting layers of wire mesh for extra strength. The wire also helps the filter retain its necessary shape after washing. This filter element is reusable – after 100K miles, you can remove it, wash it, dry it, and reinstall it without the need for re-oiling, repeating the washing as necessary.

      Built for Reliable Service. Roush’s Performance Cold Air Intake Kit is fronted by an injection molded polyethylene air box, made in the United States like the rest of the part. This air box includes an EPDM foam heat shield seal along the upper edge to provide better contact with the hood. The intake tube is rotationally molded, high density polyethylene secured by stainless steel clamps. The couplers are EPDM rubber to ensure that the intake remains in place through twisting and engine load.

      Pick Stock or 105mm MAF. The Roush Performance Cold Air Intake Kit gives you a choice between two sizes of MAF. You can choose to install it configured for a 105mm aftermarket MAF (sold separately) for maximum power gains, or with the 85mm stock MAF, which produces less power but also removes the need for a new tune.

      Bolts On with Included Hardware. Bolt-on installation is the method needed to fit the Roush Performance Cold Air Intake Kit to your F-150’s engine. This is accomplished with regular ratchet sets, wrenches, and screwdrivers, along with the kit’s hardware – no drilling or cutting is required.

      Limited 90 Day Warranty. The Roush Performance Cold Air Intake Kit is protected by a 90 day limited manufacturer’s warranty against defects.

      CARB Legal, 50 State Usable. The Roush Performance Cold Air Intake Kit meets all CARB certification guidelines and carries the CARB EO Number #D-418-30. If living in a CARB regulated area such as California, it is advisable to install the CAI so that the CARB compliance sticker is visible during engine inspection. This CARB exemption enables buying, installing, and driving with the Roush CAI in all 50 US states, making the component street-legal in all locations.

      Application. This Roush Performance Cold Air Intake Kit is specially designed to fit the 2015 to 2017 F-150s equipped with the 3.5L EcoBoost engine. It is not compatible on Raptor models.

        really worth 400$?

        this was my first time putting in a cold air intake on a car and it only took a hour long so install is pretty easy. it is louder from the engine but the power is only slightly noticeable. for the money i would i have expected better quality parts as the seal is not the best. would have gotten KandN for about 200$ cheaper if i knew

        Roush should be ashamed

        This product never even made it all the way onto my truck. The intake tube looks extremely cheap, the slot in the bottom of the air box where the factory ram air duct connects is way to big so just a cheap fit there, then to beat all the metal inserts where 2 bolts that hold the air filter tube inside the air box stripped from the plastic before the bolt was even half way screwed in. AT refunded my money and were very understanding. I would not recommend this product to anyone ever!

        Good but...

        The ROUSH cold air intake looks great under the hood, and you can really feel it when you you put your foot down. However, the install process was a bit tricky as the seal that goes around the top of the box wasn’t lining up how it was supposed to no matter what I tried, so I just drilled 2 of my own holes to make it fit. My only other little complaint it that the box doesn’t even come close to being fully sealed around either the inlet or the snorkel piece.

        performed as expected

        No real noticeable effect on performance. MPG did increase slightly, but probably will never add up to the cost of the intake over the life span of the truck

      The open element scares me. I have friends who installed open aired intakes on their cars and a week later they hydro lock the engine. The open part of the box does not seal completely when driving in rain and the water hits your engine. So is the 2017 3.5 boost completely sealed under the hood?

      • The Roush Cold Air Intake will seal completely to the hood, allowing water to enter via the OEM duct in the grille only.
