Description
Enhance your Toyota Corolla’s performance with the Injen RD Series Cold Air Intake, Part No. RD2081P. Designed specifically for 2002-2004 models equipped with a 1.8L 4-cylinder engine, this system offers a significant boost in horsepower and torque through a carefully engineered intake pathway. The mandrel-bent 6061-T6 aluminum tube ensures a smooth, restriction-free airflow route that reaches deep into the engine bay to draw in the coolest, densest air available, resulting in improved combustion efficiency and power output. This intake system not only delivers measurable performance gains but also maintains safe air-fuel ratios without the need for additional tuning, making it a straightforward upgrade for enthusiasts seeking increased engine response and a more aggressive sound.
Constructed with durability and aesthetics in mind, the Injen RD intake features a polished finish that complements the engine bay’s appearance, although a black powder-coated option is also available for a more subdued look. The included SuperNano-Web dry air filter is fully serviceable and offers increased surface area for superior airflow while providing excellent filtration to protect your engine. The intake produces an aggressive, throaty tone under full throttle, adding to the driving experience. Additionally, this system is CARB EO approved (D-476-8), making it legal for emissions-compliant vehicles in California and other states. Backed by Injen’s limited lifetime warranty, this intake system offers both performance and peace of mind, ensuring long-lasting reliability and customer satisfaction.
Whether you’re looking for an easy bolt-on upgrade or a way to improve your vehicle’s aesthetics, the Injen RD Series Cold Air Intake is a high-quality choice that combines proven technology and craftsmanship made in Pomona, California. It is compatible with the 2002-2004 Toyota Corolla models and provides a straightforward way to add horsepower, enhance engine sound, and improve overall vehicle responsiveness without the need for complex tuning or modifications.
