Product Details

If you're looking to get more out of your 2002-2004 Toyota Corolla's 1.8L engine, this Injen RD Series cold air intake is a solid option. It's designed to replace your restrictive factory airbox and tubing, giving your engine a smoother, more direct path to cooler air. This means your engine can breathe easier, which often translates to a noticeable improvement in throttle response and a bit more power, especially in the mid-range where you'll feel it most during everyday driving.

The heart of this system is the mandrel-bent aluminum tubing. Mandrel bending ensures the tube keeps a consistent diameter throughout its bends, unlike crush-bent tubing which can create restrictions. This smooth path helps pull in the coolest air available from behind the front bumper, and Injen has made sure that this improved airflow is managed safely, maintaining proper air-fuel ratios without needing a separate tune. It also comes with a serviceable SuperNano-Web dry air filter that offers good filtration and can be cleaned and reused, saving you money in the long run. Plus, you'll get a more aggressive, throaty engine sound when you step on the gas.

This particular intake is finished in a durable black powder coat, giving your engine bay a clean, custom look. Injen backs this intake with a limited lifetime warranty, reflecting their confidence in its build quality and performance.
