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.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNissan 200SX, 280ZX, 510, 720, 810, D21, Maxima, Pathfinder, Pickup\u003c\/li\u003e\n\u003cli\u003eVolkswagen Vanagon\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by the Wix 51521 Oil Filter\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrevents engine wear caused by contaminants in the oil\u003c\/li\u003e\n\u003cli\u003eReduces risk of oil starvation during engine startup with anti-drain back valve\u003c\/li\u003e\n\u003cli\u003eMaintains proper oil flow even if the filter element becomes clogged\u003c\/li\u003e\n\u003cli\u003eProtects engine components from damage due to oil pressure fluctuations\u003c\/li\u003e\n\u003cli\u003eHelps extend engine life by ensuring clean oil circulation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure the engine is cool before removing the old oil filter\u003c\/li\u003e\n\u003cli\u003eApply a thin layer of clean engine oil to the gasket of the new filter for a proper seal\u003c\/li\u003e\n\u003cli\u003eHand-tighten the Wix 51521 filter until the gasket contacts the mounting surface, then tighten an additional 3\/4 turn\u003c\/li\u003e\n\u003cli\u003eCheck for leaks after installation and during initial engine operation\u003c\/li\u003e\n\u003cli\u003eDispose of the used oil filter according to local regulations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty Information\u003c\/h2\u003e\u003cp\u003eWix filters are manufactured to meet industry standards for filtration efficiency and durability.
