Product Description

The K&N PF-3000 is a direct-replacement diesel fuel filter engineered for Chevrolet Silverado and GMC Sierra HD trucks equipped with the 6.6L Duramax diesel engine. It's built to meet or exceed OEM specifications, giving Duramax owners a reliable factory-style replacement that also emphasizes higher flow and filtration capacity than a standard OEM filter.

The filter uses a high-strength carbon steel housing with a rolled seam that exceeds OEM pressure ratings, paired with cellulose glass filter media designed to trap rust, dirt, scale, and other contaminants common in diesel fuel systems. This construction is intended to protect the fuel injection system from premature wear while supporting strong, low-restriction fuel flow.

This filter is intended for Duramax diesel owners performing routine fuel filter maintenance who want a durable, high-flow replacement backed by a long-term warranty. Installation includes a new filter head O-ring, but the factory water-in-fuel (WIF) sensor must be removed from the old filter and reinstalled on the new one, since it is not included in the kit. Given the discrepancy in sources over the exact model-year cutoff, confirm your specific Silverado or Sierra HD model year and Duramax engine code against K&N's official fitment tool before purchasing.
