Injen 17-19 Chevy Silverado 2500/3500 Duramax L5P 6.6L Evolution Cold Air Intake (Oiled Filter)

This Injen Evolution cold air intake system comes with an enclosed air box, a custom-tuned intake tube, an 8-layer oiled cotton gauze air filter, and all the necessary hardware for installation. It's designed specifically for the 2017-2019 Chevrolet Silverado 2500 HD and 3500 HD, as well as the GMC Sierra 2500 HD and 3500 HD, all equipped with the 6.6L Duramax L5P diesel engine. This system replaces your restrictive factory airbox and intake tubing to allow your engine to breathe more freely, which can result in noticeable gains in horsepower and torque.

The intake tube is custom-designed and dyno-tuned to help funnel air at a precise rate past the Mass Air Flow (MAF) sensor, ensuring accurate fuel trims and preventing check engine lights. The sealed housing uses Injen's patented Twist-Lock system to securely hold the large, 8-layer oiled cotton gauze air filter in place, making installation straightforward without needing extra parts. The housing also features a Clear-View badge, allowing for easy inspection of the air filter's condition.

Installation is designed to be hassle-free, with no cutting or drilling required, and it works with the stock engine calibration, so no aftermarket tuning is needed to see improved performance. The system is built from durable, cross-linked high-density polyethylene and includes stainless steel hardware and automotive-grade urethane couplers for a solid fit.
