Product Details

If your 2005-2007 Subaru Impreza RS 2.5L is feeling a bit choked for air, this Injen SP Series cold air intake system is designed to help your engine breathe easier. It's built to allow for deeper airflow, which can lead to the performance boost you're looking for. Injen has been a leader in tuned intake systems for a long time, holding several patents on their tuning processes, including their signature MegaRam (MR) Technology and Air Fusion. This means the intake is designed not just to let more air in, but to do so in a way that works well with your engine's computer, helping to maintain a safe air-fuel ratio while unlocking more power.

The heart of this system is the smooth, uninterrupted 6061-T6 aluminum tubing, which offers a clear path for air to reach the engine. This design is dyno-proven to deliver gains of up to 14 horsepower and 13 lb-ft of torque. It also includes a serviceable Injen SuperNano-Web dry air filter, which offers a large surface area for excellent airflow and filtration. Beyond the performance, you'll notice a more aggressive and throaty engine tone when you step on the gas.

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