The factory Air intake system on the 2500/3500 is a very unique and creative design. During testing our engineers placed multiple temperature probes throughout the engine bay and access panels of the 2500/3500 engine bay in order to find the coldest possible air source. Turns out, the 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.

Pretty quickly our team noticed that the path of the airflow was good, but quite disruptive. The air had to travel through the grille, up the radiator, through the lattice work of the shroud then around the radiator shroud and finally into the intake scoop.

This presented two problems.

1) There is no natural path for the air to flow through.

Every one of these turbulent areas, every interference causes restriction and/or causes work for the air. The goal is to get the air into and through the air intake system as cleanly and efficiently as possible.


2) The air is susceptible to being heated by the radiator.

The air must travel up the face of the radiator in order to make its way into the air intake opening. Keep in mind, the radiators operational temperature is 180-220 degrees. Significantly higher than ambient.

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 Chevrolet Silverado/GMC Sierra 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.

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.
