Injen 02-06 Nissan Altima 4 Cyl 2.5L (CARB 02-04 Only) Black Cold Air Intake *SPECIAL ORDER*

If you're looking to get more out of your 2002-2006 Nissan Altima with the 2.5L 4-cylinder engine, this Injen RD Series cold air intake is a solid option. It's designed to pull cooler, denser air from outside the engine bay, which helps your engine breathe better and can lead to noticeable gains in horsepower and torque. This kit is CARB-exempt for model years 2002-2004, meaning it's legal for sale and installation in California and other states that follow CARB standards.

The heart of this system is the smooth, mandrel-bent 6061-T6 aluminum tubing. This construction method ensures there are no restrictions in the pipe, allowing for a smooth, uninterrupted path for air entering the engine. It comes with a fully serviceable Injen SuperNano-Web dry air filter, which offers a large surface area for increased airflow and good filtration. You'll also notice an improved, more aggressive engine tone under acceleration, giving you an audible reminder of the improved airflow. This black powder-coated finish looks sharp under the hood.

This intake is a direct bolt-on installation and is designed to maintain safe air-fuel ratios without needing a separate tune. It's made in Pomona, California, and comes with Injen's limited lifetime warranty.
