Injen 2015 Subaru STi 2.5L 4 Cyl (Turbo) Polished 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 polished aluminum tubing, a custom heat shield, and a SuperNano-Web dry air filter. This Injen SP Series cold air intake is designed to let your engine breathe more freely, potentially adding up to 24 horsepower and 24 lb-ft of torque according to dyno tests. It uses Injen's patented MR Technology and Air Fusion to help maintain a safe air-fuel ratio while improving airflow.

The intake tube is made from 6061-T6 aluminum, offering a smooth path for air to enter the engine. The included heat shield helps keep hotter engine bay air away from the intake charge, ensuring cooler, denser air gets to your turbo. The SuperNano-Web dry filter is serviceable, meaning you can clean and reuse it, and it offers good filtration. You'll also notice a more aggressive engine sound under acceleration.

This intake is designed as a direct fit for your WRX STI and does not require additional tuning. It's made in Pomona, California, and comes with Injen's limited lifetime warranty.
