Product Details

This Injen RD Series cold air intake system is designed for your 1988-1991 Honda Civic or CRX Si. You'll get the polished aluminum intake tubing, a SuperNano-Web dry air filter, and all the necessary hardware and instructions to get it installed. This kit is built to collect the coolest, densest air available, feeding it directly into your engine for an improved power output.

The heart of this system is the mandrel-bent 6061-T6 aluminum tubing. Mandrel bending means the tube maintains a consistent diameter throughout its length, creating a smooth, uninterrupted path for air to flow into the engine. This helps eliminate restrictions that can slow down airflow. The included SuperNano-Web dry air filter is fully serviceable, meaning you can clean and reuse it, and it offers a large surface area for excellent airflow and filtration. Injen has also made sure that this intake helps maintain safe air-fuel ratios without needing additional tuning, and it's CARB certified, so it's legal in California.

Beyond the performance gains, you'll also notice a more aggressive and throaty engine tone when you step on the gas. This intake is made in Pomona, California, and comes with Injen Technology's limited lifetime warranty.
