This Dynamic Air Scoop takes advantage of the Challengers factory Air Catcher headlight inlet by guiding cool ambient air from outside the vehicle directly into your intake system. The cool dense air allows your vehicle to run more efficiently, increasing performance. This D.A.S. is constructed from high - quality linear low - density polyethylene (LLDPE) that is impact resistant, extremely durable, and 100 recyclable. Inspired by the Challenger SRT Hellcat, this Dynamic Air Scoop works with both factory (requires Hellcat factory airbox) and aFe POWER Momentum GT intake systems (PN 5154 - 72201 5154 - 72202 and 5154 - 72203). This part easily snaps into the air box and requires no modification to your vehicle.
