Injen EVO7008 Evolution Cold Air Intake, Chevrolet Silverado 2500/3500 2001-2004, GMC Sierra 2500/3500 2001-2004

Description

The Injen EVO7008 Evolution cold air intake is a direct-fit performance upgrade for the Chevrolet Silverado and GMC Sierra. Injen dyno testing shows gains of up to 21 horsepower and 43 lb-ft of torque. It replaces the restrictive factory intake with a less restrictive design that improves throttle response and works with the stock engine calibration.

Engineered for the Chevrolet Silverado and GMC Sierra, the Evolution system replaces the factory airbox with a durable roto-molded XLPE housing and a dyno-tuned intake tube. The enclosed box keeps heat out while providing room for one of the largest filters in its class.

A fully serviceable SuperNano-Web dry filter protects the engine in your Chevrolet Silverado and GMC Sierra. 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-1101-BB. An optional Injen Hydroshield pre-filter (1074BLK) is available for added protection from water and debris.

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.
