aFe cold-air intakes are designed to maximize air volume and velocity and produce maximum horsepower and torque. Our C5 intake, for example, made 24 additional hp and 29 lb-ft of torque.

AFE is, perhaps, the most recognized air intake manufacturer in the diesel industry. We tested the AFE Momentum HD intake for 2011 to 2014 Ford Super Duty 6.7L Power Strokes (PN 50-73005) this month.

aFe Power Pro Dry S—175.3 hp, 117.5 ft-lb of torque ($78.40 at aFe Power) ... My Civic had an Injen cold-air intake on it when I got it, and the car ran like crap.
