About this item

This kit bundles the three main filters your 2020-2025 Chevrolet/GMC 6.6L Duramax 2500HD/3500HD needs — fuel, oil, and air — so you don't have to source each one separately. Each filter is a direct cross-reference to major OEM and aftermarket parts like AC/Delco, Wix, Baldwin, and Purolator numbers. Lab-tested for filtration efficiency and dust capacity, they're built to keep your engine protected between scheduled services.

3-piece filter kit: fuel filter DGF429, oil filter D11878, and air filter DPA11888 in one box.
Fits Chevrolet/GMC 6.6L Duramax 2500HD and 3500HD, model years 2020-2025.
Cross-references: DGF429 replaces AC/Delco TP1015, Wix WF10451, Premium Guard DF99173, Purolator F21393; D11878 replaces GM 12684038, AC/Delco PF26, Wix WL10454, Baldwin B7449, Premium Guard PG9952EX; DPA11888 replaces GM 84554703, Wix WA11057, Baldwin PA10426, Premium Guard PA99537, Purolator TA31515.
Fuel filter rated 3 micron at 98.13% efficiency; oil filter rated 25 micron at 99% efficiency; air filter holds 344.2g of dust at 99.25% efficiency, per third-party lab tests.
