WIX XP Oil Filter Replacement for Synthetic Oil — 7.4L/8.1L Chev/GMC Trucks & Vans (99-12)

WIX XP Oil Filters deliver extended performance for drivers who demand engine protection under pressure. Built for synthetic oils and heavy-duty conditions, this filter is designed to work with 7.4L or 8.1L engines found in Chev/GMC trucks and vans from 1999 through 2012. Whether you're towing, navigating hills, or logging long highway miles, the XP series aims to keep lubrication moving with confidence.

Engineered for Synthetic Oils

The filter uses a next-gen synthetic-blended media with natural fibers that delivers high filtration efficiency while eliminating the need for wire backing. In tests, the media achieves up to 99% efficiency at 23 microns, based on the XP reference. This design helps maintain clean oil as it passes through the filtration stage and reduces the risk of restricted flow during demanding drives.

At the heart of the filter is a durable silicone anti-drainback valve. This feature helps ensure the first startup after a cold soak receives oil where it belongs, even when temperatures swing dramatically. The valve also helps minimize dry starts after long idle periods, supporting smoother engine operation.

Extended Performance and Fit

WIX positions this XP filter as a high-performance option that can exceed typical OE expectations in synthetic-oil applications. The design supports up to 20,000-mile change intervals when used with synthetic oil, making it well-suited for long-haul routines or owners who prefer longer service windows.

Designed for a precise fit, the XP filter is easy to install and intended for both DIY enthusiasts and professional mechanics. Quick, confident installs reduce downtime and simplify maintenance routines. Before purchase, verify vehicle compatibility by checking the fitment information to ensure the correct filter for your vehicle.
