Sinister Diesel’s new Cold Air Intake for the 2007.5-2009 Dodge Ram 6.7L Cummins engine features build and material specs unlike other intakes on the market. For example, instead of the usual plastic tubing, Sinister uses mandrel bent aluminum for maximum strength, airflow and heat dissipation. In addition, rather than using industry standard rubber couplers, Sinister uses superior silicone couplers for longevity. Filter to turbo connectivity is another feature that delivers top performance, along with a polished and powder coated finish for durability and a clean look under the hood. To ensure quality control, Sinister fabricates the new intake in-house at their Sacramento, California area facility. Easy installation completes the long list of features truck owners will appreciate. In addition to the new 6.7L Cummins intake, Sinister also manufactures intakes for Ford Powerstroke engines.
