Injen 02-05 Civic Si Polished Cold Air Intake

When you open the hood of your 2002-2005 Honda Civic Si, you want to see parts that look as good as they perform. This Injen SP Series cold air intake system is designed to do just that, giving your engine a smoother path to breathe in more air. You'll get the polished 6061-T6 aluminum intake tubing, a serviceable SuperNano-Web dry air filter, and all the necessary hardware and instructions to get it installed.

This intake is built around Injen's patented MR Technology, which helps tune the intake for optimal performance gains while keeping your air-fuel ratio safe. The smooth, uninterrupted path of the aluminum tubing helps eliminate restrictions that the factory intake can create, leading to improved airflow. Injen's dyno testing shows gains of up to 12.1 horsepower and 12.7 lb-ft of torque with this system, and you'll also notice a more aggressive, throaty engine tone under acceleration.

This system is designed as a direct fit for your Civic Si, meaning no additional tuning is required after installation. The SuperNano-Web dry filter is serviceable, so you can clean and reuse it for the life of the intake. Injen backs this intake with a limited lifetime warranty.
