Product Information
The aFe Momentum GT cold air intake system for the 6.6L gas V8 (L8T) HD trucks uses a one-piece sealed housing with a built-in sight window, so the filter can be checked without taking the airbox apart. A CAD designed, roto-molded intake tube connects to the throttle body through a silicone bellows coupling and T-bolt clamps, and the Pro 5R filter uses five layers of oiled cotton gauze. It is rated at up to +14 hp and +14 lb-ft over the factory intake. Before installation, the truck's Air Filter Life System is reset to 100% and then disabled.
