Detailed Description of Wix 51391 Engine Oil Filter

The Wix 51391 engine oil filter is specifically designed for use in Chevrolet and Suzuki vehicles such as the Grand Vitara, Tracker, Vitara, and XL-7. Featuring an anti-drain back valve, this filter prevents oil from draining out of the filter when the engine is off, reducing wear during startup. The enhanced cellulose media material provides effective filtration at a 21-micron rating, capturing contaminants while allowing sufficient oil flow. The filter’s bypass relief valve is calibrated at 16 psi to ensure oil continues circulating even if the filter becomes clogged, protecting the engine from oil starvation. With a burst pressure of 360 psi, the filter maintains structural integrity under demanding conditions. Its spin-on design and standard 3/4-16 thread size make installation and replacement straightforward for maintenance professionals and DIY enthusiasts alike.
