Upgrade your Honda Civic Si with the Injen Technology RD Series Black Cold Air Intake, designed to deliver noticeable horsepower gains and enhance engine bay aesthetics. Crafted from mandrel-bent 6061-T6 aluminum, the intake tube provides a smooth, restriction-free airflow path that reaches deep into the engine bay to draw in the coolest, densest air possible. This efficient airflow increases power output while maintaining safe air-fuel ratios, eliminating the need for additional tuning. The intake includes a fully serviceable Injen SuperNano-Web dry air filter, which offers increased surface area for enhanced airflow and superior filtration, ensuring optimal engine protection and performance.
The aggressive, throaty engine tone produced under full throttle delivers a satisfying driving experience that enthusiasts will appreciate. The intake system is available in a sleek black powder-coated finish, providing a personalized and durable aesthetic that complements your vehicle’s look. In addition, the kit includes all necessary hardware and detailed instructions for straightforward installation. Built in Pomona, California, and backed by Injen’s limited lifetime warranty, this intake system combines quality, performance, and reliability. It is also CARB EO approved (D-476-3), making it a compliant upgrade for California emissions standards.
Designed specifically for 1999-2000 Honda Civic models, this Cold Air Intake improves airflow efficiency, engine sound, and overall performance without the need for complex tuning. Whether you're looking for increased horsepower, a more aggressive sound, or an eye-catching engine bay upgrade, the Injen RD Series intake offers a comprehensive solution that meets high-performance standards and provides long-lasting durability.
