Injen 2015 Subaru STi 2.5L 4 Cyl (Turbo) Black Cold Air Intake w/ MR Tech and Heat Shield

When you open the hood of your 2015-2017 Subaru WRX STI, you'll see the Injen SP Series Cold Air Intake system. This kit includes the smooth, black 6061-T6 aluminum intake tubing, a custom-designed heat shield to keep engine heat away from the intake air, a serviceable SuperNano-Web dry air filter, and all the necessary hardware and instructions for installation.

This Injen intake is built around their patented MR (MegaRam) Technology, which is designed to help your engine breathe deeper and improve performance safely. The smooth aluminum tube offers a less restrictive path for air compared to the stock setup, and the included heat shield helps ensure that the air entering the engine is cooler, which can lead to more power. Injen claims dyno-proven gains of up to 24 horsepower and 24 lb-ft of torque with this system, while also working to maintain a safe air-fuel ratio. You'll also notice a more aggressive and throaty engine tone when you step on the gas.

This intake is made in Pomona, California, and comes with Injen's Limited Lifetime Warranty. It's designed as a direct fit, meaning no additional tuning is required after installation.
