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.

Easy to install, great performance. The sound is noticeable even without the tune. The reason I bought this was the removable venturi so I can do with or without the tune.Helpful (0)

Car idle issues
The intake is nice but I think it’s a issue due to bad catalytic converters but the car will idle up to 2k when driving and I put n neutral. I talked to roush about it and they said it would be my fault and that I installed wrong. I didn’t. I used diagnostic scan tool to check for any issues. Nothing is bad but the cats. Hopefully that’s the issue and not the intakeHelpful (0)

GREAT upgrade! But.... if you're like me, that just want a little more performance, looks, and sounds, keep in mind this dropped my mpg's from 19.8 mpg to 14.9 is it worth it? I would say yes ! The performance this gives is amazing you can notice the change in acceleration. And also the sound of the air its sucking in is amazing! Along with the roush cat-back, every time I turn on my GT it's music to my ears!Helpful (4)

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.
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.
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.
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.
From my understanding, it will not.
Unfortunately, we haven't heard talks of Roush making a cover the '15-'17 Mustangs like they do for the '18-19. We would recommend reaching out to Roush as they may have that information for you. As for your concern regarding water getting on the filter, it shouldn't cause any damage, unless the filter is either drenched in water or submerged.
To clean Roush Cold Air Kit filter you can just use pressurized water. You can also use a filter cleaner.
The Ford Performance GT350 5.2L Voodoo Intake Manifold will be a complete intake manifold, as opposed to the Roush Cold Air Kit which is the intake tubing that goes to the intake manifold. The Roush Cold Air Kit will be a direct drop in and will work well in your stock RPM Range. The Ford Performance GT350 5.2L Voodoo Intake Manifold will raise the power band higher into the RPM range, and will require a tune to function properly, as well as a specific cold air, or modified cold air if it was not originally designed for the intake manifold.
This cold air kit will be compatible with the SCT Livewire tuner.
Yes, that device/tune can be used for this intake.
You would want to go with a Roush brand filter, however we do not currently carry a replacement at this time.
No Computer Tune Required with MAF/Venturi Insert Tube Installed, however if this is not installed a tune will be required.
