The HSP LMM Cold Air Intake for your 2007.5-2010 GM 6.6L Duramax LMM adds a custom look under the hood while increasing performance! Featuring 4" mandrel bent pipe, HSP's intakes increase flow by removing restriction while also pulling in cold, fresh air from the headlight bezel and fender port. The heat deflection box provides an air tight seal which prevents hot engine temps from entering through the intake. Proven dyno numbers show an increase of 20HP and 58 lb x ft. torque!
