Upgrade your 2017-2019 GM Diesel truck with the Injen Evolution Cold Air Intake System, designed specifically for the Chevrolet Silverado and GMC Sierra with the 6.6L L5P Duramax engine. Crafted in the USA from durable cross-linked high-density polyethylene, this intake system offers proven performance gains without the need for aftermarket tuning. Its roto-molded sealed housing features the innovative Injen Twist-Lock System, which securely attaches the large 8-layer oiled cotton gauze filter, simplifying installation and ensuring a tight seal for maximum airflow efficiency. The system's sleek design enhances under-hood aesthetics with the new Injen Clear-View badge and an aggressive profile that maintains an OE-like fit. The intake tube, custom-designed and dyno-tuned, directs airflow at optimal rates past the MAF sensor, providing increased horsepower and torque while preserving stock calibration. Engineered to produce significant performance improvements, the EVO7007C system delivers up to 34 horsepower and 76 lb-ft of torque gains, along with a commanding intake growl under acceleration. The system includes stainless steel band clamps with inner protective liners, a fully serviceable Injen SuperNano-Web dry air filter, reinforced silicone couplers, and all necessary hardware for a straightforward installation. Please note this product is not CARB-exempt and is intended for off-road use only. Made in Pomona, California, the Injen EVO7007C is backed by a limited lifetime warranty, ensuring durability and performance for your heavy-duty truck upgrade.
