Enhance your Subaru WRX or STI's performance with the Mishimoto 08+ Subaru WRX/STI Performance Cold Air Intake Kit. Designed specifically for 2008 and newer models, this kit replaces the restrictive factory airbox to deliver increased horsepower and torque. Our engineers spent months refining this intake to maximize airflow and optimize engine response, resulting in dyno-proven gains of approximately 25 horsepower and 25 torque at 5300 rpm. The kit is a straightforward bolt-on upgrade that installs in under an hour and works seamlessly with the factory tune, making it an ideal choice for enthusiasts seeking quick, reliable power improvements.
Constructed with a mandrel-bent aluminum intake pipe, the kit features a choice of a polished, red, or black powder-coated finish to match your vehicle’s aesthetic. The intake pipe incorporates a Mishimoto air straightener and a CNC-machined mass airflow (MAF) sensor housing, ensuring accurate and consistent readings for a smooth power band and optimal engine performance. To keep intake temperatures low and prevent heat soak, the filter is positioned outside the hot engine bay, protected by a powder-coated heat shield. The included Mishimoto oiled air filter has a larger surface area—offering 16-percent greater airflow capacity—and provides effective filtration of dirt and debris, contributing to sustained performance and longevity.
This kit includes all necessary hardware, such as silicone couplers and clamps, for a quick installation. The free-flowing air filter is fully serviceable, allowing for a lifetime of reliable use. Additionally, the aggressive intake tone adds a satisfying sound that enhances the driving experience. Proudly made in the USA, the Mishimoto Subaru WRX/STI Performance Cold Air Intake Kit comes with a Mishimoto Lifetime Warranty, ensuring quality and durability for years to come.
Compatible with a variety of Subaru models including the Impreza WRX and STI from 2008 to 2014, this intake upgrade is an excellent choice for drivers seeking improved throttle response, increased power, and a more exciting sound from their vehicle.
