LBZ Duramax Cold Air Intakes

Maximize airflow, lower exhaust gas temperatures (EGTs), and improve turbo spool-up on your 2006–2007 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LBZ Duramax cold air intakes. While the 6.6L LBZ is renowned for its power and reliability, the factory airbox and paper filter quickly become a restriction when you add performance tuning, upgrade your turbo, or tow heavy loads. Upgrading to a high-performance cold air intake replaces the restrictive OEM plumbing with large-diameter, smooth-flowing intake tubes and high-capacity filters encased in heat-shielded or fully enclosed airboxes. This allows your engine to draw in a higher volume of cold, dense air, resulting in sharper throttle response, enhanced turbo whistle, and superior engine protection against dust and debris. Whether you prefer the low maintenance of a dry disposable filter or the longevity of a washable oiled filter, we have the perfect setup for your driving conditions. We supply industry-leading cold air intake systems from top aftermarket manufacturers like S&B Filters, aFe Power, Banks Power, and Mishimoto.
