    Review & Install Video

    Stephanie with AmericanMuscle.com here with my review of the Roush Cold Air Intake Kit available for the 2015 and up Mustang GT. The Roush Cold Air Kit is going to be for the S550 GT owners out there who are looking to have a little bit of flexibility with their cold air intake. A cold air intake is normally one of the first mods that many Mustang owners go to, but a lot of times the question of "Is a tube required?" has an impact on the intake that is chosen. This intake from Roush has a Venturi tube that's going to change the MAF 4, thereby giving the option of needing a tune or not depending on the setup you have chosen to run. Either Venturi tube installed or not, which makes it unique. Now gains are going to change depending on the MAF air flow or MAF 4 that you've chosen to run. But speaking of gains, let's see what kind of gains you can expect before we get any more into the intake. We already got a baseline run today from our 2015 GT. So we are now going to spin the car again with a Roush intake installed with no Venturi insert so the 105 millimeter MAF 4 and a 93 octane tube because if you're not going to run the insert you definitely need to run a tube. Our baseline run with our 2015 GT gave us numbers of 395 horsepower and 361 foot-pounds of torque at the rear wheels. With the Roush intake and tune installed, those numbers change to 411 horsepower and 387 foot-pounds of torque making for a peak gain of 16 horsepower and 26 foot-pounds of torque. Now keep in mind that we did pair the intake with a tune so a lot of these gains can definitely be attributed to that tune. Our gains throughout the curve showed as much as 28 horsepower and 28 foot-pounds of torque right in the 5000 and 5500 RPM range. These are the gains that you're actually going to notice when you're driving, especially in this RPM range. Now, we did run the car with a Venturi tube installed just to see what kind of gains we can expect on the 85 millimeter MAF air flow. We did pair it with a tune because even though you don't necessarily need one if you're running the insert, we know that we're going to see the best performance and the most gains when we do pair a cold air intake with a tune. A cold air intake alone without a tune isn't going to net large gains, probably somewhere in the single digits when it comes to horsepower gains. But what we ended up seeing here was about five horsepower and 15 foot-pounds less of torque with the insert in and the same tune installed. But this is still going to be a good option for those who are not quite ready to step up to a tune yet. Let's look a little bit more at the intake itself. The first thing I noticed was that the filter was actually pretty large and bigger than some of the other filters that are out there on other cold air intakes that I have seen. It is a reusable high flow, dry air filter which is nice because when it gets dirty, you can clean it and re-install it and not have to worry about the oiling process or getting oil on your MAF. The intake also fits nicely, and I think it looks better under the hood than the stock air box does for sure. Another cool thing here is that the air box does still keep the air feed from the grill which actually brings in air from outside the car. This is nice to see from an open air box because it does bring in the cooler air from outside the engine compartment. I like that they have tapped into that factory cold air duct here. The other thing you will notice here is that the Roush intake does eliminate the sound tube that the factory intake has. This leads to the most difficult part of the install which I'll talk about more in a minute, but just a heads up that Roush gives this little plug to plug up the firewall right behind the head so you won't have a hole where the sound tube enters the cabin. So talking a little bit more about the Venturi tube here. This is a Venturi tube here, and basically what it's going to do is change the MAF 4 of the intake. With the tube installed, the MAF 4 will be 85 millimeters which will not require a computer re-tune. A lot of the computer re-tune is based on the MAF size of these aftermarket intakes. Now, that's not to say that you can't run a tune with the tube installed, as you saw earlier. Without the Venturi tube installed, the MAF air flow size is obviously going to be much larger, 105 millimeters to be exact, which will definitely require a tune. So just to go over this one more time. If you run the Venturi tube, you don't necessarily need it tuned, but if you don't run the tube, then you do need a tune for sure. And that is how Roush is offering an intake that gives you the option of running a tune or not, depending on how you set it up. Looking at the price for this intake, it costs right in between $300 and $400, being slightly closer to that $400 mark which is right in line with other intakes, like AIRAID and JLT. When it comes to the install, it's nothing too difficult and all you really need is a few sockets and a flat head for the plastic pin. The most difficult part, like I mentioned earlier, is taking out that stock sound tube because there are parts of it that can be hard to get to. Roush does say to take out the entire sound tube and plug the firewall, but there could be a way to get around removing the entire sound tube if it seems like too much trouble for you. Or if you want to able to easily revert back to a stock setup. You can find a plug out there to plug the second half of the sound tube so you don't have to completely remove it, just as a little tip. I'm still going to call this a one out of three wrenches on the scale, and it should take you about an hour to complete the install. Wrapping things up here, this intake from Roush is a good quality option that fits and looks great and gives the user an option as far as which MAF air flow size they like to run. If you run the Venturi tube, you don't need a tune. But if want to run the larger MAF size, then you will need a tune. The intake, when paired with the tune is certainly going to increase power and improve the driveability of the S550 GT, and you can check it out more for yourself online right here at AmericanMuscle.com.

    Increase Horsepower and Torque. The Roush Performance Mustang Cold Air Intake kit replaces your 5.0L GT Mustangs restrictive stock air box and paper filter with a high flow filter assembly and intake tube for an increase in horsepower and torque while improving throttle response and fuel mileage. Power gains of 28 horsepower and 28 torque have been seen with the stock tune and the 85mm MAF/Venturi Insert Tube installed. More power is possible by removing the MAF/Venturi Insert Tube for a 105mm MAF bore and adding a custom tune.

    No Tune Required. Unlike other Cold Air Intakes on the market for the GT Mustangs this Roush CAI does not require a computer re-tune when installed with the included venturi insert tube. If the venturi insert tube is not installed a new tune will be required for operation. In that case AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for operation.

    Reusable High Flow Dry Filter. The included Roush High-flow Dry Air Filter provides excellent filtration of harmful particulates. It is composed of two layers of wire mesh for durability and is proven to retain its shape even under high airflow. This dry air filter is washable and does not require oiling, saving you time and money.

    Straight Forward Installation. The Roush Performance Cold Air Intake Kit is designed to install easily with just basic hand tools. No extra modifications or special tools are required for proper installation. All necessary parts and instructions are included.

    Application. This Roush Performance Cold Air Intake kit is specially designed to fit the 2015-2017 GT Mustang's equipped with the Coyote 5.0L DOHC V8 engine. No computer retuning required for operation with the venturi insert tube installed. The Cold Air Intake will B>not fit on Roushcharged Mustangs.

    Technical Note. This Roush Cold Air Intake is not legal for use in California or other states adopting California emission standards.

    5 Top Rated Questions

    Which have given better gains the Air raid CAI or the Roush CAI with and without a tune?

    • I ended up sticking with the Roush CAI. The Roush CAI would most likely have the better gains with a tune. Without a tune it's very questionable on both of them, but most people will tell you if you don't plan on tuning at some point, a CAI is probably not the way to go to see power gains. For me personally, without a tune there is still an increase in throttle response and there are definite cooler inlet air temps while moving, but for me the decision came from the deletion of the sound tube and knowing I can achieve more power with a tune if I so choose. I've seen up to 25-40 hp and 20-35 ft lbs of torque to the wheels (85mm insert removed) with a tune for the Roush. However it is very difficult to base actual gains off of dyno numbers because most of them are running in abnormal conditions ie: hood open, adding fans for more air flow, etc.

    Does this void the Mustangs factory warranty?

    • The Magnusson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, was created to protect consumer warranties. According to this act, a manufacturer such as Ford cannot void the warranty of a vehicle due to the use of an aftermarket part unless they can prove the aftermarket part directly cause or contributed to the failure of the vehicle.

    Curious about water issues with the "open top" cold air intakes on the 2015 GTs with heat extractors. There is one right above where this would sit the the engine bay. Rain, car washes... water gets into those openings...

    • After installing mine and the rainy season under way, I've noticed water does come through the heat extractors but not as much as you would think. It's ok for the filter itself to get wet but not totally drenched or submerged like shooting a garden hose into your engine bay. I usually put some plastic or a trash bag over mine while I wash mine though, but for normal driving conditions in the rain, you should be fine.

    In the description of this product it is stated that gains of 28 horsepower and gains of 28 ft. pounds in torque have been seen with stock tune. The video states that these horsepower and torque numbers are only achieved with a tune. Can you please clear this up?

    • To clarify a bit, with the Roush Cold Air Kit, you will see gains of 28 horsepower and 28 torque with a pre programmed tune(stock tune) and the (85mm) venturi insert tube installed. You can see more gains by removing the venturi tube (105mm) and adding a custom tune.

    hello, this cai its in my list to put on my gt, however I'm a little worried about how the heat vents are right above the air filter, Question ¿can water get into the filter ?

    • The design of the Roush Cold Air Kit could allow some water to pass through the vents onto the filter, however the design of the vents prevents major water intrusion, and we have not seen any issues caused by this.

      Installation was easy but my only complaint is that it doesn't come with all the necessary hardware needed. They assume you're going from a factory air box and will have all the stock items like bushings. I went from a different cold air intake from another company and the bushings weren't needed with that one ( I bought the car like that) So now I'm trying to find these bushings. For $400, Roush should include all parts needed.

      Kit has wrong elbow for 2016 GT

      American Muscle has been great to work with. The kit came with an elbow that was incorrect for my 2016 GT. The range it was supposed to fit was 2015,2016 and 2017. The part must have changed during that span. I ordered it a second time and returned the second kit when the same incorrect part came in the second kit. I contacted Roush directly they recognized the issue and sent me the part directly so my install actually took a week and a half when it could have been finished in about 4 hours. Both American Muscle and Roush were helpful in trying to solve my issue. If you have a 2016 GT read the instructions before installing and make sure the number of barbs on that elbow match the number of hoses you should have at that stage of the installation. In my case I went from 4 hoses to 3 hoses and the elbow only had two barbs it should have had 3. Most likely for a newer mustang than my 2016.

      Rush cold air kit purchase and installation

      The purchase was easy and I was pleased to see that I did not need a custom tune after installation. However, installation was not "easy" as the ad said. I have a GT convertible with strut stabilizers and that made installation very tedious. If I had written the instructions I would have said to take them off first. Still I could not get to the resonance induction tube to remove it. Lots of bruises later I finally am in business. Took almost three hours to finish. There were no installation instructions in the package and the one I downloaded off the Roush site was incomplete, left out some steps I had to figure out myself. But my Mustang has a lot more pep, especially in third gear, and I hope the MPG goes up as well.

      Roush cai

      Love this C.A.I by Roush. Fits and looks OEM. The hardest part of this installation was the sound tube delete. You're gonna need some 1/4 in drive extensions and a swivel for your deep well socket to get the sound tube nut off the stud behind the driver side head on the fire wall. Other than that its easy. It uses the old hardware and bushings and lines up perfectly. It's a huge visual difference under the hood. Not only does it draw air from the grill but it also draws air from your hood vent on the driver side. I also love this because you can run it with or without a tune you have that option. It was packaged very well and came very quickly from American Muscle. I'm very happy customer and will continue to purchase buy upgrades from American Muscle, thanks again. Andrew from Indiana

      Roush delivers

      I was dubious as to similar reviews on other CAIs but Roush made me a believer! I’m not very mechanically inclined, so I enlisted my neighbor’s help. When he was a No Show, I plunged ahead.... granted it took me over an hour, probably due to the sound tube plug, but I got it done and there was a noticeable difference. Roush always has it dialed in!

      Roush never fails

      This cold air intake fit perfectly and has added noticeable power and sound without a tune. I plan on using a tune later on to unlock it's full potential but it's a good upgrade straight out the box. Hardest part of the installation is removing the stock intake, mainly the sound piece that for some reason Ford decided to mount to the firewall. Twas a pain getting that sucker off and if you don't have a super set of tools i suggest doing this install while the engine is cool because youre gonna have to get your arm deep into the engine to get the stock intake uninstalled. But after you get the factory intake out you basically just toss the Roush intake in and start rolling.
