Mishimoto Cold Air Intake Polished w/ Air Box 2015-2021 WRX

Unlock the full potential of your 2015-2021 Subaru WRX with the Mishimoto Performance Air Intake, engineered specifically for your vehicle to improve airflow, turbo response, and overall performance. Designed with high-quality materials and innovative components, this intake ensures your WRX breathes easier while maintaining safe air/fuel ratios.

The intake features a wire-reinforced lower induction hose that prevents collapse under suction and boost, paired with a high-flow oiled air filter that offers more filtration surface area than the stock paper filter. This filter is cleanable and reusable, providing a lifetime of reliable performance. The enclosed airbox protects against engine bay heat soak while maintaining a stock-like appearance. The intake integrates seamlessly with your factory intake duct to deliver cool air to the turbo, enhancing spool and performance while producing an aggressive tone under acceleration.

Dyno testing shows maximum gains of up to 33 whp and 30 wtq, with peak gains of 28 whp and 21 wtq while maintaining safe AFRs. With a proper tune and 93-octane fuel, this intake can achieve up to 70 whp and 70 wtq on a 6-speed WRX, all while safely supporting your engine. Installation is simple and can be completed in about one hour using common hand tools.
