Product Details

When you open the hood of your 2005-2007 Subaru Impreza RS, you'll see a polished aluminum intake tube, a SuperNano-Web dry air filter, and all the necessary hardware and instructions to get it installed. This kit is Injen's SP Series cold air intake, designed to help your engine breathe easier and make more power.

The heart of this system is the 6061-T6 aluminum tubing, which is polished for a clean look and shaped to provide a smooth, uninterrupted path for air entering your engine. Injen has patented their tuning process, using technologies like MegaRam (MR) and Air Fusion to ensure that the intake not only increases airflow but also maintains a safe air-fuel ratio across the entire RPM range. This means you get noticeable power gains, with dyno tests showing up to 14 horsepower and 13 lb-ft of torque, without compromising your engine's health. The included SuperNano-Web dry filter is serviceable, meaning you can clean and reuse it, and it offers excellent filtration.

Beyond the performance improvements, this intake also changes the sound of your engine, giving it a more aggressive tone under acceleration. Injen backs this intake with a limited lifetime warranty, and it's made in Pomona, California.
