Injen 99-00 Honda Civic Si Black Cold Air Intake

This Injen RD Series cold air intake is made specifically for your 1999-2000 Honda Civic Si. It's designed to help your engine breathe easier, which can lead to noticeable gains in horsepower and a more aggressive sound under acceleration. The engineers at Injen focused on creating a system that bolts on easily and maintains safe air-fuel ratios without needing extra tuning.

The heart of this intake is the smooth, mandrel-bent aluminum tubing. This construction method ensures there are no restrictions in the pipe, allowing air to flow freely into the engine. The tube is positioned behind the front bumper to draw in the coolest, densest air possible, which is key for performance. It includes a serviceable Injen SuperNano-Web dry air filter that offers a large surface area for maximum airflow and good filtration. This black powder-coated finish also adds a clean look to your engine bay.

Beyond the performance improvements, you'll also hear a distinct, throaty tone from your engine when you step on the gas. This intake system is made in Pomona, California, and comes with Injen's limited lifetime warranty.
