Full Cold Air Intake Kits

Maximize engine airflow, lower your exhaust gas temperatures (EGTs), and significantly improve turbo spool on your 2007.5–2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LMM Duramax full cold air intake kits. The factory airbox and restrictive intake piping on the 6.6L LMM were designed to minimize engine noise rather than optimize performance, severely choking the turbocharger when you add aggressive aftermarket tuning or haul heavy fifth-wheel trailers. This lack of clean oxygen results in sluggish acceleration, reduced fuel economy, and dangerous EGT spikes under heavy loads. Upgrading to a complete cold air intake kit replaces the restrictive factory components with massive high-flow air filters, smooth-flowing silicone couplers, and aerodynamically designed intake tubes that draw in cold, dense air from outside the hot engine bay. These simple bolt-on kits provide an immediate increase in horsepower and torque while unleashing an aggressive turbo whistle. We supply premium cold air intake systems from trusted industry leaders like S&B Filters, aFe Power, Banks Power, and HSP Diesel.
