2020-2026 GMC Sierra 2500HD Engine & Performance

Cold air intakes guaranteed to fit your 2020-2026 GMC Sierra 2500HD. Covers both the 6.6L L8T gas V8 and 6.6L Duramax L5P diesel, with options from S&B, K&N, AFE, and Banks Ram-Air.

Will a cold air intake throw a check engine light or void my warranty? No. These intakes use MAF-calibrated tubes and OE-style sensor mounting to prevent CELs, and federal law (Magnuson-Moss) protects your powertrain warranty unless the part is proven to cause a failure.

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