The Wehrli Custom Fabrication Stage 2 High Flow Intake Bundle Kit for 2007.5-2010 LMM 6.6L Duramax Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks combines a Stage 1 High Flow Bundle and Stage 2 Intake Kit. This system is designed to increase airflow to the turbo and engine, improving efficiency, throttle response, and turbo spool-up. It replaces restrictive factory plastic components with heavy-duty 14-gauge aluminum parts, including a 4-inch intake pipe with air box enclosure, a dry filter assembly, an Outerwears pre-filter cover, and a 4.8-inch turbo intake horn (providing 20% airflow improvement over stock).
