Lower Intake Air Temperatures: These Dynamic Air Scoops lower air intake temperatures by forcing more cool air from behind the front grilles into the factory intake tracts. Durable LLDPE Construction: They are constructed from high-quality linear low-density polyethylene (LLDPE) that is impact resistant, extremely durable, and 100% recyclable. Their blue color adds a colorful accent visible behind the vehicle's kidney grilles. Hassle-Free Installation: These air scoops are installed through the front kidney grille openings and are secured to the reinforcement support bar with the included plastic push-in rivets. They sit right in front of the radiator and are designed to fit with the factory radiator. No modifications are required for installation with factory and aFe POWER intake systems. aFe POWER Dynamic Air Scoop D.A.S.
