    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.

    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.

    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.

    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...

    6Bolt

    • 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.

      Rubber seal clips

      I have to say I am disappointed with the overall quality of the product. The directions were not as clear as they should be, sometimes even confusing. A better step by step set of directions is needed. Placing the rubber seal over the air box was a nightmare. It didn’t matter which way you tried to snap them all in, it just didn’t match. I had a mechanic look at it and he had the same problem. Not all the holes match up. I called tech support and was told I could carefully remove some ot the clips and make new openings so the seal would fit correctly. Are you kidding me! I spent an hour with my friend carefully relocating several of the clips so the seal would fit properly. Shouldn’t someone at the plant make sure all the clips line up correctly with the appropriate seal?

      Great filter

      Power gain isn’t overwhelming, filter fits nice and everything should take about an hour to install, with a nice BAMA tune it adds some nice horsepower and some nice miles per gallon. Great addition. Note: if you have a 16’ GT with the air vents in the hood it will leak water into it, cover the hole in the hood is my best bet. It’s almost always summer here in California so I don’t have to worry much but do note it.

      Nice CAI

      This is a real nice CAI. The only problem was getting to the bolt on the firewall. You will need a deepwell 10mm 1/4" socket a few long extensions and a swivel. But after that its a breeze! The only thing I did not like was that the "ROUSH" was supposed to be in the plastic as in the picture. The one I got they sent me a sticker. So did not like that part

      Very nice

      Looks good, I can tell a little bit of a difference in the temp of the air coming in. It did change the sound a small bit when I got rid of the resonator. Took no longer than 20 mins to put in, the hardest part was a bolt that had to come out that held the resonator in. It was behind the engine and there was very little room to get my arm back there let alone a wrench.

      Roush CAI

      Like what everyone else has stated, the intake was easy to install except for the removal of the sound tube. The install time took a little over an hour and a half because I was teaching and having my 13 year old son help me. I don't know how everyone else does it but without my son's little hands, I couldn't have gotten that rubber grommet on the firewall without removing things. The fit and finish is good. Mine doesn't say Roush on the filter housing like all the other customer pictures I've seen. My '17 GT PP is stock with 300 miles so I haven't noticed any power gains and no difference in sound or how it revs either.

      Excellent intake

      The sound tube was a pain to take out. But everything else was very easy. Would’ve taken about 10 minutes if wasn’t for the sound tube. Sound isn’t that much louder but you can definitely tell under acceleration. As for power and torque you actually do feel a nice little increase.

      Love it!

      Install was simple except for the sound tube delete, but that’s Ford’s fault, not Roush! The CAI itself only took about 20-25 mins to get on after opening the box. The tube took about an hour and a half because of the location. The intake looks great, helps you feel a bit better throttle response, and definitely improves airflow. I have it paired with a Cat Back 3” exhaust, which had some pops from the back pressure in the system before the intake, but the Roush CAI helped even out the the airflow throughout the torque band, and it sustains pressure even with quick changes to the throttle position. I also love that I can run without a tune for now, but have the option to remove the Venturi tube if I want to add mods or tunes down the road. Brilliant design by Roush!

      I like that I can upgrade this later when I'm ready to get a tuner from American Muscle and didn't have to put out all the money at once for intake and tuner. Great fit and finish. Most difficult part of the install is getting the 10mm nut off the sound tube at the firewall but end result is well worth it.

      This product works as advertised. Be aware the left heat vent on the hood drips rain water directly on the filter. I talked to the manufacturer and they confirmed it. No redesigns in the mix yet. Mine got very wet and sucked in water. I had to make a metal cover for the filter. Just be aware is all.
