Injen 98-99 RS 2.5L Polished Cold Air Intake

Injen Technology is known for making well-built performance parts, and this RD Series cold air intake is a prime example for your 1998-1999 Subaru Impreza RS 2.5L. This system is designed to give your car a noticeable boost in horsepower and a more aggressive sound, all while keeping your air-fuel ratios safe without needing extra tuning. It’s a solid way to get more out of your engine.

The heart of this intake is the smooth, mandrel-bent 6061-T6 aluminum tubing. This design creates an uninterrupted path for air, allowing your engine to breathe easier and pull in cooler, denser air from behind the front bumper. It’s paired with a fully serviceable Injen SuperNano-Web dry air filter, which offers a large surface area for maximum airflow and effective filtration. You’ll not only feel the power gains but also hear a throaty, aggressive tone when you step on the gas.

This intake comes in a polished finish to look sharp under the hood and includes everything you need for installation, including hardware and instructions. It’s backed by Injen's limited lifetime warranty, so you can be confident in its durability.
