The aFe Takeda Attack Stage 2 Pro Dry S cold air intake systems' in-house dyno testing resulted in max gains of +21 hp and +24 lbs.-ft. of torque, outflowing factory intakes by 56 percent. Their CAD-designed roto-molded red intake scoop captures coolest air available; while a high-quality ABS plastic heat shield blocks unwanted engine heat. The intakes are offered in 2.75 in. polyethylene or mandrel-bent aluminum tubes to improve volumetric efficiency for better performance. The Pro DRY S air filter features three layers of oil-free progressive synthetic media for maximum convenience. No cutting or drilling on factory parts is required for installation; all clamps, coupling, and hardware are included for a direct bolt-on.
