Add some quick horsepower to your WRX or STI with the new Mishimoto Subaru WRX/STI Performance Cold-Air Intake. This WRX cold-air kit is engineered specifically for your 2008 - 2014 Subaru WRX or STI and includes everything needed to replace the restrictive stock airbox.
Our engineers spent months fine-tuning this design in an attempt to squeak out every last bit of performance. This dyno-proven WRX cold-air intake provides 25 hp/25 tq gains over the stock intake while maintaining safe air/fuel ratios, perfect for some extra punch on the street or autocross course.
The mandrel-bent aluminium intake pipe is available with a red or black powder-coated finish or a polished aluminium finish. This pipe utilizes the Mishimoto air straightener and CNC-machined mass airflow sensor (MAF) housing to provide accurate and consistent MAF readings, which translates into a smooth power band. To reduce air intake temperatures (IATs), the air filter has been placed outside the hot engine bay, and a powder-coated heat shield prevents any heat-soak from occurring. The Mishimoto free-flowing air filter provides a 16% greater surface area, optimal airflow, and proper filtration of dirt and debris.
