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) venturi insert tube installed. More power is possible by removing the venturi tube (105mm) 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 Bama 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.

Does this void the Mustangs factory warranty?

PalmiroA

  • 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.

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

gunny42

  • 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.

Can I remove the 85mm maf bore Venturi insert to make it 105mm once I buy the roush flash pack ?

JP

  • That's correct, with the venture insert removed it will make it 105mm maf housing, however, it would need a custom tune for it to work, so once the tune is uploaded, the insert could be removed.

I'm debating over this intake or the gt350 intake, what will provide better gains? I'll be adding the gt350 tb and Im at some point and don't want to purchase an intake twice.

NikF

  • 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.

    Easy. Instant gain noticed

    I've read the reviews and read that some people weren't noticing a difference after the install. This made me a little hesitant to purchase, but I'm glad I did. I noticed immediate change in sound, acceleration and performance. I have the Scavenger X-Pipes and the Flowmaster American Thunder exahsust. I'm wondering if the people that didn't notice any change are running stock pipes? I purchased this kit due to the fact that no tune is needed with what I call "stage 1". When you're ready to pick up more ponies (and void your warranty) simply remove the inner tube in the air box, run a program, and boom! I wanted to stay Ford friendly so I purchased the Roush. Excellent buy. 5 stars

    The intake seemed to help throttle response a little, unless it's in my head. Install was easy, minus the firewall nut. Can't really hear the intake because exhaust is too loud, but quieter in cabin with sound tube delete!

    Love the new Roush cold air filter. My son and I installed it on his 2015 mustang GT in less than an hour and we are far from being mechanics. Love how it looks and performs. Favorite part is that we can easily modify it later when he decides to add a tuner.

    Indecisive!

    I receive the Roush CAI and became indecisive about the purchase. Will rain get in through the heat extractor vent? The answer is no! I have been through several rainy days with no rain getting in. Yes when washing the car if I blast the heat extractor vent what water a little gets in. So with a little care when washing no water gets in. This was a great buy for several reasons. 1) It looks great! 2) The inside of the car it's much quieter thanks to the sound tube delete. 3) and when the warranty is up, I can remove the insert and add a tune!

    I own a speed shop and this is probably one of the best ideas for a intake in the market. I bought this intake because I wasn't looking to buy a tune right away. I love how it comes with the insert for the intake tube to run factory tune till I decide tuning for my car. It was a 15 min install if that and fits just like factory. highly recommend

    Everything and more.

    This breather was exactly what I wanted and more. Opened the intake right up with noticible gains in power and sound. I'm hoping to get even better performance with by allowing more air under the hood with a new set of MMD grilles as well - I find there to be a lot of heat that gets built up in the bay... You'll notice the biggest difference in sound when you hammer down the gas, she growls more aggressively, sounding more like classic muscle. Removing that single bolt that holds the sound tube to the firewall was definitely the most difficult and frustrating part. I got through it using two 10" extension bars, and a swivel. It would be easier if you could use a short socket but the stud is obnoxiously long. Beyond the performance gains, this intake looks phenomenally better than you stock airbox. It came with a few sets of white Roush decals, and if you do it right, you can have them set perfectly into the stamped logo on the breather, which looks super SHARP. Most definitly worth every penny, and would recommend to anyone that wants that nice bump in performance gain without any tuning, ontop of a huge jump in cosmetic enhancement.

    HIGH QUALITY COLD AIR INTAKE

    I'm pleased with the quality of the Roush cold air intake but disappointed with the lack of instructions in the package. I've noticed a slight difference in throttle response and I'm still waiting for improvement in mileage. It took about an hour and a half to install due to the difficulty of removing the air tube from the firewall. I'd recommend this intake to anyone looking to purchasing an intake.

    Simple install but it was hard to remove the air tube to the cabin so They could put the plug in. To tight of a location. But other than that I have notice better gas mileage. Not really horsepower difference since I did not have it tuned. Did not want to void warranty just yet. Maybe closer to 35k.

    I want to start off saying I also owned the air raid intake for the 11-14 mustang gt, the quality on the Roush is by far the best I have seen, the Roush lettering on the intake box can be left off for a factory appearance. Great purchase. Sounds amazing.. This intake also removes the sound tube so you don't have another hole on the intake tube to plug.
