Provide increased airflow to your WRX or STI with the Mishimoto Subaru WRX/STI Performance Air Intake. Mishimoto designed this intake to be as non-restrictive as possible, featuring a straight 2.75" short-ram intake pipe and designed with maximum airflow in mind. 

Engineered to fit on either your stock or Mishimoto turbo inlet tube, this intake is also compatible with most aftermarket front-mount intercooler kits. Due to the size of the intake pipe, a retune of your vehicle's ECU is necessary to keep your engine running safe and extracting the most horsepower from the added airflow. The intake pipe also features a CNC air diverter to provide consistent airflow readings to the MAF sensor, making retuning quick and easy. The intake pipe is available in a polished finish to accent any engine bay. A 2.75" diameter Mishimoto high-flow air filter is also included. This filter is specially designed for the small engine bay of the WRX/STI and features a built-in velocity stack for maximum flow. The intake is designed to reuse the stock intake duct to provide fresh outside air to the filter. The Mishimoto Subaru WRX/STI Performance Air Intake comes with all of the necessary clamps, couplers, and hardware for an easy install. The Mishimoto Performance Air Intake will give your Subaru WRX or STI a highly-aggressive intake tone under acceleration.
