Injen SP1946P SP Series Polished Cold Air Intake, Nissan Maxima 3.5L V6 2004-2008

Description

Upgrade the factory air intake on your Nissan Maxima with the Injen SP1946P SP Series cold air intake. Injen dyno testing shows gains of up to 11.3 horsepower and 16 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.

At the heart of every SP Series intake is Injen's tuned-intake engineering. The 6061-T6 aluminum tube used on the Nissan Maxima is designed to reduce restriction and turbulence, and Injen validates each design on the dyno so power increases arrive without compromising air/fuel ratios. This kit incorporates Injen's patented MegaRam (MR) Technology and Air Fusion to help maintain safe air/fuel ratios while maximizing gains.

A fully serviceable SuperNano-Web dry filter protects the engine in your Nissan Maxima. The synthetic media offers excellent filtration efficiency and can be cleaned and reused, with no filter oil to manage. When service is due, order Injen replacement filter part number X-1015-BB. An optional Injen Hydroshield pre-filter (1033BLK or 1033RED) is available for added protection from water and debris.

The polished aluminum finish adds a bright, show-quality look to the engine bay. Beyond the performance gains, the intake adds a satisfying induction sound and a clean under-hood appearance. Injen stands behind the quality of its parts with a Limited Lifetime Warranty for the original purchaser.

CARB Legal: This Injen intake is exempt under California Air Resources Board Executive Order D-476-5, covering 2004-2008 model years, and is legal for use on emissions-controlled vehicles in all 50 states within that coverage.
