GMC Sierra 3.0L Duramax Cold Air Intake

Let your baby Duramax breathe. This Cold Air Intake system for the 3.0L Turbo Diesel features a fully enclosed airbox to keep out hot engine bay air. The huge oiled-cotton filter flows 50% more air than the restrictive stock paper filter. The intake tube is roto-molded to smooth out the airflow path to the turbo inlet, resulting in faster spool-up times and improved throttle response. Dyno-tested gains of 12 HP and 22 lb-ft of torque. The clear lid allows for easy filter inspection without disassembly.
