Mishimoto Air Intake System w/ Air Box 

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.
