Injen RD1975BLK RD Series Black Cold Air Intake, Nissan Altima 2.5L 2002-2006

Description

Upgrade the factory air intake on your Nissan Altima with the Injen RD1975BLK RD Series cold air intake. Injen dyno testing shows gains of up to 7 horsepower and 7 lb-ft of torque. This direct-fit system is engineered to improve airflow, sharpen throttle response and add an aggressive induction sound without additional tuning.

The RD Series is Injen's race-derived cold air intake. On the Nissan Altima, a mandrel-bent 6061-T6 aluminum tube reaches down into the engine bay to collect cooler, denser air, providing a smooth path that supports stronger bolt-on power.

Filtration is handled by Injen's SuperNano-Web dry air filter, a synthetic, fully serviceable element that captures fine particles while providing a large surface area for airflow. No oiling is required, which keeps sensors on the Nissan Altima clean. When service is due, order Injen replacement filter part number X-1014-BB. An optional Injen Hydroshield pre-filter (1033BLK or 1033RED) is available for added protection from water and debris.

A durable black powder-coated finish gives the engine bay a clean, understated look. The system provides a deeper, more aggressive intake tone under full throttle and installs with basic hand tools. Injen designs and manufactures its intakes in Pomona, California, and backs them with a Limited Lifetime Warranty.

CARB Legal: This Injen intake is exempt under California Air Resources Board Executive Order D-476-5, covering 2002-2006 model years, and is legal for use on emissions-controlled vehicles in all 50 states within that coverage.
