Mishimoto has developed a performance air intake specifically for the 2015 Subaru WRX. The Mishimoto intake features a wire-reinforced lower induction hose that will not collapse under suction and boost. 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, all on the stock tune. With the Mishimoto tune kit more dyno testing showed results of up to 70 whp with 93 octane fuel while maintaining safe AFRs. This 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.
Mishimoto has utilized the 2015 WRX stock intake duct 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 intake is available with an enclosed airbox for protection against engine bay heat-soak that will retain a stock-like engine bay appearance. This is a complete bolt-on intake that functions perfectly with the stock WRX tune and can be installed in about an hour with simple tools.
