2020-2026 GMC Sierra 2500HD Air Filters

Air filters that fit the 2020-2026 GMC Sierra 2500HD, both the 6.6L L8T gas V8 and the 6.6L Duramax LML/L5P diesel. Stocked options include K&N drop-in panel filters, AFE Pro Dry S, S&B reusable cotton-gauze, and full cold-air intake systems from Banks and AIRAID.

Will an aftermarket air filter or intake void my Sierra 2500HD warranty? No. Under the Magnuson-Moss Warranty Act, GM cannot void your powertrain warranty unless the filter is proven to cause a specific failure, and CARB-compliant options keep you smog-legal in all 50 states.

Every filter listed here is verified against your Sierra 2500HD -- no guesswork.
