    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.

    I have this installed on my 17 gt when at idle the inlet temp rises to about 30-40 degress over outside temp but when driving it stays about 3-4 degress above , you know the reasoning for this ?

    • The Roush Cold Air Kit draws in fresh air via the grille, and will be able to pull in more cool air when moving, lowering the intake air temperature. When stationary, the air around the grille will be heated by the radiator, allowing intake air temps to increase.

      Roush Cold Air 0n 2017 Mustang GT

      First up the Roush Cold Air Kit arrived with all parts and packaged great. The only thing that would help on installation would be printed installation instructions. I did go on the Roush web site but could not find the instructions to print out. But the videos on the American Muscle website were great. The product fit Factory perfect looks like it should have come from the factory this way. Performance sounds very good combined with my Borla Ford catback exhaust. I wasn't expecting big gains yet. I will be adding larger Throttle Body and tune. the cold air kit will come into play big time then.

      GET IT!!!!!!!!

      I’ve waited a week to review this product. So far it’s amazing. Stock intake air inlet temperature driving would range 125 degrees and air inlet to the engine would be around 11. Since the install my temperature dropped 20/30 depending on the day. Usually the temperature would range from 95 to 100 which that means colder air which means denser air which equals more hp and my air inlet to the engine is around 14 which equals more air to the engine. Get this and you won’t be disappointed I promise.

      Great outcome, great decision made only because it allows you too have the inner tube for the Mass Air Flow Sensor not too trigger a "check engine light" but when your ready too have your car dino tune just take that inner tube out and you'll be all set.

      heat shield

      I didn't feel like the heat shield sealed against the hood as well as I would like so I purchased some foam pipe insulation. It comes split down the middle so I secured it on top of the rubber seal that was provided essentially making it thicker and taller. That provided a very good seal albeit perhaps not the most aesthetically pleasing. The result was about 2 degrees better than stock. I know this because I just bought a 2018 and compared the intake temps.

      Love it!

      I put this in together with the Flowmaster Outlaw axle backs and I’m loving it! Noticeable increase in power (not a ton, but still noticeable), runs cooler, and averaging about 30mi more out of a full tank. I drive 120mi for work daily so I like to track my mpg. Removing the sound tube was a pain in the a**. I recommend a long wrench with adjustable head angle. Other than that, rest of install was easy. I did not buy with the tune because I plan to get a different tuner but it’s still worth the buy.

      Nice addition to the S550

      Removing the stock airbox takes longer than installing the Roush intake. The sound tube removal was a royal pain, and that took a bulk of the installation time. Paired with a tune, and it improved the sound of the exhaust a little as well. Looks good under the hood, and everything fit perfectly. Well worth it when paired with a tune. Not sure how much usable horsepower gain you will get just by itself.
