What is the benefit of a cold air intake?

A cold air intake system helps your engine produce more power by drawing in cooler, denser air from outside the engine bay. The smooth, mandrel-bent tubing in this Injen system also reduces restrictions compared to the factory airbox.

Does this intake require tuning?

No, this Injen RD Series cold air intake is designed to provide power gains while maintaining safe air-fuel ratios without the need for additional engine tuning.

How do I maintain the air filter?

The included Injen SuperNano-Web air filter is fully serviceable. You can clean and reuse it, and replacement filters are available separately.

Product Details

This Injen RD Series cold air intake is built with a smooth, mandrel-bent 6061-T6 aluminum tube. This design helps create an uninterrupted path for air, allowing your 2002-2004 Toyota Corolla's 1.8L engine to breathe easier. By drawing in cooler, denser air from behind the front bumper, this intake can help increase horsepower and give your engine a more aggressive sound under acceleration.

The system includes a fully serviceable Injen SuperNano-Web dry air filter, which offers a large surface area for greater airflow and effective filtration. Injen has also ensured that safe air-fuel ratios are maintained throughout the powerband, so you don't need to worry about additional tuning for basic bolt-on power gains. This intake is available in a polished finish, as shown here, or a black powder-coated option.

This intake is made in Pomona, California, and comes with Injen Technology's limited lifetime warranty. It's a CARB-exempt system, meaning it meets California Air Resource Board standards.
