Detailed Description and Technical Specifications

The Wix 51521 engine oil filter is engineered with enhanced cellulose media that effectively traps contaminants down to 21 microns, helping to protect engine components from wear. Its anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing dry starts and extending engine life. The filter’s bypass relief valve activates between 8 and 11 psi, allowing oil to bypass the filter element if it becomes clogged, ensuring continuous lubrication. Rated with a burst pressure of 325 psi, this filter withstands high-pressure conditions common in heavy-duty applications. The spin-on design with a 3/4-16 thread size simplifies replacement on compatible Nissan and Volkswagen vehicles.
