Mishimoto has developed a performance air intake engineered specifically for the 2015+ Subaru WRX. The intake features numerous innovative components, including 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 on the stock tune. This intake has a unique and aggressive tone under acceleration and boost, and the free-flowing design amplifies turbocharger spool and BPV sounds. The stock 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 intake is optionally 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 that functions perfectly with the stock tune and can be installed in one hour using common hand tools. Made in the USA and available with either polished or Wrinkle Black aluminum intake piping, this kit includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
