The Mishimoto Performance Air Intake is designed to improve airflow, throttle response, and turbo sound on the 2008–2014 Subaru WRX and STI while maintaining dependable daily drivability.

This intake system increases airflow efficiency compared to the factory intake by reducing restriction and improving air delivery to the turbocharger. The result is quicker throttle response, improved turbo spool, and a more engaging driving experience without sacrificing reliability. Designed to balance performance and usability, this intake delivers noticeable gains without the downsides commonly associated with overly aggressive intake setups.

Developed by Mishimoto, the system features durable intake piping and a high-flow air filter engineered for consistent airflow and long-term use. Expect a deeper, more pronounced induction sound under boost while maintaining smooth operation during normal driving.

Whether you’re refreshing an aging factory setup or building a foundation for future performance upgrades, the Mishimoto Performance Air Intake is a solid upgrade for the EJ-powered WRX and STI.
