Injen 04-09 Mazda 3 2.0L 2.3L 4 Cyl. Polished Cold Air Intake

Injen is known for making performance parts that add power and sound, and this RD Series cold air intake is a great example for your 2004-2009 Mazda 3. If you're looking to get more out of your 2.0L or 2.3L engine, this intake is designed to help. It works by giving your engine a smoother, less restricted path to draw in air, which can lead to noticeable gains in horsepower and torque.

The heart of this system is a polished, mandrel-bent 6061-T6 aluminum tube. Mandrel bending means the tube keeps a consistent diameter throughout, which helps air flow more freely without turbulence. This tube reaches into the engine bay to pull in the coolest, densest air possible, especially when placed behind the front bumper as this design allows. It includes a serviceable Injen SuperNano-Web dry air filter that offers good filtration and allows for increased airflow. You'll also notice an improved, more aggressive engine tone under acceleration.

This intake is designed to maintain safe air-fuel ratios without needing a separate tune. It's also CARB exempt for most applications, meaning it meets stricter emissions standards. Injen backs this intake with a limited lifetime warranty, so you can be confident in its build quality.
