AEM has released its BRUTE FORCE HD intake system for 2007 Cummins-equipped 6.7L Dodge Ram pickups (part# 21-9221DS). Given the tight tolerances of the 6.7L-equipped Ram's engine compartment and the inlet pipe's proximity to the exhaust manifold, AEM manufactures the 21-9221DS's inlet pipe using roto-molded polypropylene. Unlike polyethylene piping, which is used by some competitors, polypropylene is more heat resistant and will ensure that the extreme temperatures of the exhaust manifold do not affect the integrity of the inlet pipe.
