Our 75-5116 air box is huge and was engineered to maximize all the available space, providing better performance and more breathing room for a larger filter. The air filter for this intake was designed to snap into place for easy installation and an air-tight seal that won't degrade over time. Premium silicone was used to build this kit's filter, inlet, coupler and tube sleeve. Silicone can withstand temps up to 400? and won't crack or tear with age. A billet-machined aluminum mounting adapter ensures the MAF sensor is installed properly. The 75-5116 intake kit for the 2017-2018 Silverado 1500 and Sierra 1500 trucks fits like a glove inside the engine bay and easily outperforms the stock system.
