Product Description

The Injen RD2037P RD Series Cold Air Intake System is a direct-fit performance upgrade engineered for 2000-2004 Toyota Celica GT models equipped with the 1.8-liter inline-four engine. This intake replaces the restrictive stock airbox with a smooth mandrel-bent 6061-T6 aluminum tube and high-flow SuperNano-Web dry air filter to deliver cooler, denser air into the engine for improved airflow and throttle response. Dyno testing shows gains of up to approximately 12 horsepower and 12 lb-ft of torque, all while maintaining safe air/fuel ratios without the need for additional tuning.

Installation is straightforward with the included hardware and instructions, and the polished finish enhances engine bay aesthetics. The RD2037P produces a more aggressive induction sound under acceleration, enhancing the driving experience. This cold air intake is backed by Injen Technology's limited lifetime warranty and has CARB Executive Order D-476-8, making it legal for sale and use in states requiring CARB compliance where applicable. Always verify local emissions regulations before purchase.
