K&N 2015 Subaru WRX-STI 2.5L H4 Red Typhoon Short Ram Intake

If you're looking to get more out of your 2015-2017 Subaru WRX STI's 2.5L engine, a K&N Typhoon Short Ram Intake is a solid option. This system is designed to replace your restrictive factory air box and intake tubing with a smoother, mandrel-bent aluminum tube and a high-flow air filter. The goal here is to let your engine breathe easier, which can lead to a noticeable increase in both horsepower and torque.

The K&N High-Flow Air Filter uses oiled cotton gauze media, which is washable and reusable. This means you can clean it and reinstall it for years of service, with K&N suggesting up to 100,000 miles between cleanings under normal highway driving. The kit includes a custom heat shield to help block hot air from the engine bay from getting sucked into the intake, keeping the air entering your engine cooler and denser. Installation is typically straightforward and can often be completed in under 90 minutes with basic tools.

Keep in mind that this intake system is not CARB approved and cannot be shipped to California. It's protected by K&N's Million Mile Limited Warranty.
