Description:
The WIX Spin-On Lube Oil Filter 51040 delivers consistent, high-quality filtration for a wide range of Chevrolet and GM cars and trucks (1976–2017), as well as Daewoo (1999–2002) and Saab (1994–1998) models. Built with enhanced cellulose media, this full-flow filter captures harmful contaminants while maintaining steady oil flow and pressure throughout the lubrication system. The anti-drain back valve prevents oil from draining during shutdown to reduce dry starts, and the robust housing ensures reliable operation even under high temperature and pressure. With a 325 PSI burst pressure rating and no bypass valve, this WIX filter delivers dependable OEM-level performance for both daily and demanding driving conditions.
