2015+ WRX Air Intake System w/ Air Box by Mishimoto

Dyno testing showed maximum gains of up to 33 whp and 30 wtq and peak gains of up to 28 whp and 21 wtq while maintaining safe AFRs. Dyno testing also yielded results of up to 70 whp with the Mishimoto tune kit and 2015 WRX intake with 93 octane fuel while maintaining safe AFRs. This 2015 WRX intake has a unique and aggressive tone under acceleration and boost, and the free-flowing design amplifies turbocharger spool and BPV sounds. Check out the sound video to hear the tone.

The stock 2015 WRX intake duct is utilized to provide cool airflow to the high-flow Mishimoto oiled air filter, which features increased filtration surface area compared to the stock paper filter. This filter can be cleaned and reused, providing a lifetime of service. The 2015 WRX intake is available with an enclosed airbox for protection against engine bay heat-soak, and it provides a stock-like engine bay appearance as well. This unit is a complete bolt-on to your 2015 WRX and can be installed in one hour using common hand tools. Made in the USA and available with either polished, wrinkle black, or wrinkle red aluminum intake piping and, like our entire line of 2015 WRX parts, includes the signature Mishimoto Lifetime Warranty.

Work as described. Got that woosh sound now.

Not bad install. Took me longer then usual just because i like to take my time. I installed it with out lifting the car. I really enjoy the car even more now. Is worth it just for the sound itself but can help with future upgrades. It seems i still needed to transfer one of the oem worm clamp that goes to the turbo inlet but no big deal.

As advertised

Quality setup, comes with all the hardware needed, fairly self explanatory installation but does have videos available for finer points. In my opinion there has been 0 power gain and a slight dip in mileage because it sounds fantastic and I can’t keep my foot out of it. Finally sounds like a turbo car. 10/10 would buy again, mishimoto is best bang for the buck at this time

Great Intake

This was the only C.A.R.B legal intake I was able to find, but it was one of the best purchases I have made for my car. It only took a little over an hour to install and sounded amazing with lots of cool BPV sounds.

Awesome and easy

Install for this part is beyond easy, just take your time and DO NOT fully tighten the worm gear clamp until you have everything fit correctly. That leads me to the next part, the airbox, the airbox location sits pretty far forward, so you have to make sure you are not going to have box set up so the air scoop touches the filter through the box opening (reason you dont tighten all the clamps). After the install I used cobb’s stage 1+ mishimoto OTS map and it runs great, no knock events and good DAM readings and the difference is easily noticeable. The sound from the intake is awesome when under boost and the temps are definitely lower. Couldn’t be happier with this awesome product, and thank you MAPerformance for being one of the few companies to have this in stock.
