More Power and Better Performance. A tried and true way to improve the power and performance of any Coyote powered GT Mustang is by installing a high flow cold air intake and a custom tune file. That is why AmericanMuscle offers this convenient Steeda ProFlow CAI and X4 VMP Tuner combination kit. A Steeda Cold Air Intake with a VMP Custom Tune is a dyno proven way to make more horsepower and torque across the entire rpm band while improving throttle response and overall engine performance.

Steeda ProFlow Cold Air Intake. Utilizing a CNC mass air housing to obtain the cleanest mass air signal on the market, this Steeda ProFlow Cold Air Intake completely replaces the restrictive stock air box and paper filter element. Coupling a reusable nanofiber air filter and roto-molded intake tubing, this CAI system delivers impressive increases in throttle response and power, all while providing excellent filtration of contaminants.

SCT X4 Tuner With VMP Tunes. The SCT X4 Handheld Tuner allows you to re-tune your S550 Mustang's computer for an increase in power and better drivability so you can take full advantage of your new Steeda ProFlow Cold Air Intake. When you order this combo, you aren't just getting a tuner - you are getting the tuner and 1 Custom Tune that are written specifically for your Mustang and your particular modifications by VMP Tuning. VMP Tuning even provides one post sale datalog review (if necessary) to assure your Pony is running healthy and strong. See more info about this X4 Tuner - Here

Increase Your Mod's Potential. From the factory, Ford programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. That is why a custom tune file is so important, by optimizing the air/fuel ratio, adjusting ignition timing and tweaking variable cam timing, a VMP Tuning Custom Tune will squeeze out the extra power your aftermarket performance mods have to offer.

Application. This Steeda ProFlow Cold Air Intake and SCT X4 Power Flash Tuner with 1 Custom Tune File by VMP Tuning is specially designed to fit the 2015-2017 GT Mustang's equipped with the coyote 5.0L 4 valve V8 engine with or without basic bolt-on upgrade modifications such as a Throttle Body and/or Full Exhaust System.

Technical Note. The included Steeda CAI is not legal for use in California or any other states adopting California emission standards. Intended for off-road, track use only.

**Please Note: The SCT SF4/X4 Tuner ships blank from AmericanMuscle, the custom tune files will be emailed directly to the end user within 5-7 business days from VMP Tuning.

    Took about an hour to install. Installed it outside in the pitch black so it should have probably taken less time then that, but this intake along with a tune definitely gives the car a nice feel now. It will bark the tires all the way through 3rd gear with 275's on the rear. Worth it!

    Not so cold.

    This intake is manufactured relatively well, though for what you pay you wouldn’t expect to have to modify or use parts off the stock intake. The CNC billet MAF housing looks excellent, but contributes to higher intake air temperatures if you’re at a standstill, like a day to day commute where you encounter traffic, and/or traffic lights. I don’t expect any cold air intakes to actually run cooler than the stock intake, as that was never more than five to seven degrees warmer than ambient air even at idle, but I understand that the volume of air is what contributes to the power increase. At just above idle after being at a stop light and watching intake temps go up to 143, you can feel some hesitation when you go to take off. The coupling from the MAF housing to the throttle body tube is of some concern as it didn’t quite fit well, along with the fitting-and-grommet combination for the PCV, and vacuum lines. They’re not held in by anything besides just a very slight pressure. I actually almost lost one because it popped off while trying to put the fitting through it. They’re not terribly secure. Then there’s the rubber seal for the air filter housing to hood. Dear lord. The bends in the air filter housing were definitely not designed with the weatherstripping in mind. It is absolutely atrocious and will not fit well. It is not very pliable and will not stay put. You can either choose to have it sit on the straight parts of the housing or on the curves. Not both. I haven’t yet received a tune for this intake from VMP. Still waiting the 7-10 days, but I used both the SCT tune on the device for a stock engine. Felt a very very minimal difference. When I installed the intake and ran that tune, however, it was definitely night and day difference. The power curve feels totally different and the ability to move the rev limiter just a couple hundred more revs is very welcome, as it provides you with adequate time to shift before hitting the soft limiter that cuts power. All in all, while this intake paired with a tune definitely, definitely makes power, I would purchase a different intake. This is probably the best looking and by far the least branded intake on the market, though, and that partially contributes to why I purchased it. Honestly, I could forgive all the other faults, but the metal MAF housing is what makes me feel like I cannot strongly recommend this product, as well as being less finished and having to reuse a part of the stock intake. It’s thrifty where it needs to be and flashy where it doesn’t, but perhaps like Steeda claims, the metal housing provides a much better, truer reading and is the reason why it performs as well as it does. I’m teetering on three and a half stars, but the actual power delivery when paired with just a standard SCT tune makes me round upwards towards four stars. It’s a tough call because I genuinely think I would prefer to go for an enclosed, all plastic and silicone intake.

    Great first mod!

    Install was fairly straight forward. Updating the tuning device was easy. Everything goes together as one would expect. (Everything's very tight under the hood.). I could tell there was an increase in acceleration and throttle response. Customer service was great from AM, and VMP.

    Great first mod

    This is the first mod that I bought for my new 2017 5.0. Between the intake and the tune, it definitely opens up the top end more. I was told to expect around a 20whp gain and you can feel it, especially revving it out. Intake temps have also dropped. Overall, a great product for a great price, especially compared to what other sites have this package selling for. I'm glad to see AM partnering with well a respected coyote tuner like VMP also.
