Holley's iNTECH cold air intake brand represents the highest degree of technology, performance and style for late model cars, trucks and SUV's. This system is designed for the popular 2019-2021 GM Silverado/Sierra 1500 trucks with the 5.3L V8 and produced +7 HP and +13 lb.ft. of torque on the dyno. It features a patented Slip-Seal housing-filter-tube interface that eliminates the use of hose clamps and adapters at the filter housing for a seamless installation. The large, high-flow, washable and reusable 4-layer dry air filter eliminates the use of filter oils that can damage MAF sensors and set off check engine lights. The use of factory mounting locations and emissions controls makes for an easy installation and the housing design is styled to match the engine compartment of your vehicle for a stealthy appearance.
