Show original supplier description

The K&N 63-3085 cold air intake system is engineered to replace the restrictive factory air filter and air intake housing in 2014-2018 Chevrolet Silverado and GMC Sierra 1500 vehicles equipped with the 4.3L engine. By reducing air intake restriction and straightening airflow, this system allows your engine to breathe more freely, resulting in increased horsepower and torque. The system uses the factory mass air sensor and crankcase vent hose, and the oversized cone-shaped air filter can last up to 100,000 miles before requiring service, depending on driving conditions. Installation is straightforward, typically taking around 90 minutes or less using common hand tools. Key features include an open box design and a black intake pipe. The replacement filter for this system is K&N RU-1041. Please note that this product is not 50-state legal and cannot be shipped to California.
