Upgrade the performance of your 2017, 2018, or 2019 Chevrolet Silverado 2500HD / 3500HD or GMC Sierra 2500HD / 3500HD equipped with the 6.6L Duramax L5P V8 diesel using the Cold Air Inductions 512-0110-B Cold Air Intake System. This dyno-tested cold air intake replaces the restrictive factory air box to deliver improved airflow, sharper throttle response, and enhanced overall drivability for heavy-duty diesel applications.
Engineered specifically for the demands of the Duramax L5P, the system features a textured black powder-coated aluminum intake tube paired with a sealed aluminum air box that draws in cooler, denser outside air to improve combustion efficiency and reduce heat soak. A clear inspection window allows for quick filter checks without disassembly, while the reusable high-flow oiled cotton-gauze air filter provides excellent filtration and long-term engine protection in both work and towing conditions.
This bolt-on cold air intake installs in under an hour using basic hand tools, requires no tuning, and is backed by a Limited Lifetime Warranty. Proudly designed, engineered, and built in the USA for reliable performance, durability, and precise OEM-style fitment.
