Subaru WRX/STI 2008–2014 Mishimoto Performance Cold-Air Intake

Add some quick horsepower to your WRX or STI with the new Mishimoto Subaru WRX/STI Performance Air Intake. This kit is engineered specifically for your 2008– 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 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 Mishimoto Subaru WRX/STI Performance Air Intake includes everything needed for installation, installs in under one hour, and works perfectly with the stock tune. 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. The included Mishimoto oiled air filter is completely serviceable, allowing for a lifetime of reliable use. Additionally this kit includes a silicone coupler, clamps, and all other hardware necessary to complete a quick installation for easy bolt-on power. Along with an upgrade in power, this intake also provides an aggressive and rich intake tone that is a huge improvement over the stock intake. The Mishimoto Subaru WRX/STI Performance Air Intake is designed and made in the USA and includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
