The factory Air intake system on the GMC Sierra 1500 is a very unique and creative design. During testing our engineers placed multiple temperature probes throughout the engine bay and access panels of the Sierra engine bay in order to find the coldest possible air source. Turns out, GMC engineers did a pretty good job of finding a great source of fresh air. Knowing that repositioning the air intake would not be beneficial our team of designers began looking at ways to improve the airflow and find additional benefits.

To solve the two problems with this otherwise fantastic design the design team at Stillen began by creating a proper scoop. This scoop lowers the base of the radiator shroud to be in line with the top bar of the famous GMC grille. This new design allows for the air to come directly into the intake system without being warmed by the radiator, or disrupted by the lattice type material in the radiator shroud. This design eliminates the pre-heating and the turbulence caused by the factory system.

During our development our team noticed that the factory ? and 1 ton trucks actually have scoops in their radiator shroud designs also which confirmed that the True Power by Stillen cold air intake scoop for the GMC Sierra 1500 was on the right track!

An additional benefit to this air intake is that it will work with any aftermarket air intake system that utilizes the factory air intake scoop.
