2020-2026 Chevy Silverado 3500HD Engine & Performance

Cold air intakes engineered for the 2020-2026 Chevy Silverado 3500HD, covering both the 6.6L L8T gas V8 and the 6.6L L5P Duramax diesel. Shop sealed-airbox kits from S&B, AFE, K&N, and Banks with reusable oiled or dry filter options.

Will a cold air intake void my Silverado 3500HD warranty? No -- the Magnuson-Moss Warranty Act protects you, and reputable brands like S&B and AFE are CARB-compliant or 50-state legal when the EO number is listed on the product page.

Verified fitment on every listing -- if it shows here, it bolts to your HD.
