Collection: 2020-2026 GMC Sierra 3500HD Cold Air Intakes

Cold air intakes engineered for the 2020-2026 GMC Sierra 3500HD, fitting both the 6.6L L8T gas V8 and 6.6L Duramax L5P diesel. Shop sealed-airbox systems from S&B, K&N, AFE Power, and Banks with washable cotton or dry synthetic filters.

Will a cold air intake void my powertrain warranty? No. Under the Magnuson-Moss Warranty Act, GM cannot deny your warranty simply for installing an intake -- they must prove the part caused the specific failure being claimed.

Verified fitment for your Sierra 3500HD, no guesswork.
