Injen 99-00 323 E46 2.5L 99-00 328 E46 2.8L 2001 325 2.5L Polished Cold Air Intake

Starting with the smooth, mandrel-bent 6061-T6 aluminum tubing, this Injen RD Series cold air intake is built to help your BMW breathe easier. This intake is designed to reach behind the front bumper to pull in the coolest, densest air possible, which can lead to noticeable improvements in horsepower and torque. Injen dyno-tested this system and found gains of up to 9.6 horsepower and 10 lb-ft of torque, all while making sure your air-fuel ratios stay safe without needing a tune.

The heart of this intake is the fully serviceable Injen SuperNano-Web dry air filter. Its large surface area allows for greater airflow while still providing excellent filtration. You'll also notice a more aggressive and throaty engine tone when you step on the gas. This polished finish looks sharp under the hood and is a popular choice for BMWs from 1998-2001, including models like the 323i, 328i, and 325i.

This intake system is made in Pomona, California, and comes with Injen Technology's limited lifetime warranty. It's also CARB EO certified, meaning it meets emissions standards in California and other states that follow its regulations.
