Product Details

If you've got a 2002 or 2003 Nissan Maxima and you're looking to get a little more pep out of your 3.5L V6, this Injen RD Series cold air intake is a solid option. It's designed to pull cooler, denser air from behind the front bumper and feed it directly into your engine, which can help with both power and throttle response. Injen has put in the work to make sure this intake maintains safe air-fuel ratios, so you don't have to worry about extra tuning right out of the box.

The heart of this system is the mandrel-bent aluminum tubing, which Injen uses to create a smooth, uninterrupted path for air. This helps reduce restrictions compared to the stock intake. It also comes with a serviceable SuperNano-Web dry air filter that offers good airflow and filtration. You'll likely notice a more aggressive, throaty sound when you step on the gas, and Injen's dyno testing shows gains of up to 28 horsepower and 28 lb-ft of torque. This polished finish also adds a nice touch under the hood.

This kit includes everything you need for installation, including the tubing, filter, and hardware. It's also CARB approved, so it should be street legal in California and other states that follow CARB standards. Injen backs this intake with a limited lifetime warranty.
