The factory air path on the Silverado and Sierra 2500/3500 is clever but not exactly direct. Air enters through the grille, climbs the face of the radiator, passes through the lattice of the radiator shroud, and only then reaches the intake scoop. That route adds turbulence, and it also lets the radiator, which runs somewhere between 180 and 220 degrees, warm the air before it gets to the engine.
The TruPower scoop from STILLEN leaves the factory intake location alone and fixes the path to it. It lowers the base of the radiator shroud so it lines up with the top bar of the Chevrolet Silverado and GMC Sierra grille, which lets air flow straight into the intake without crossing the radiator or the shroud lattice. It has a textured finish to match the factory look, and it works with any intake or supercharger that uses the factory air intake scoop.
