Technical Details and Performance

The Wix 57521 oil filter features enhanced cellulose media that effectively filters particles down to 22 microns, helping to protect engine components from wear. Its bypass relief valve setting at 19 psi ensures continuous oil flow even when the filter is clogged or oil is thickened by cold temperatures. Rated with a burst pressure of 320 psi, this filter withstands high-pressure conditions common in heavy-duty diesel engines. The spin-on design simplifies replacement, while the 1 1/2-12 thread size ensures compatibility with specific engine models requiring this specification.

Compatible Vehicles and Applications

This engine oil filter is compatible with a range of heavy-duty trucks and commercial vehicles that require a 57521 filter with the specified dimensions and thread size. It is commonly used in diesel engines where a high flow rate and robust filtration are necessary to maintain engine longevity and performance.

• Protects against engine wear caused by contaminants
• Prevents oil starvation during cold starts or high-pressure conditions
• Maintains consistent oil flow in heavy-duty engine applications
• Reduces risk of engine damage from clogged filters

Installation Notes and Tips

Ensure the engine is cool before removing the old filter to avoid burns. Verify the thread size and filter dimensions match the vehicle’s requirements. Apply a thin layer of clean engine oil to the gasket before installation to ensure a proper seal. Tighten the filter according to manufacturer torque specifications to prevent leaks. Since this filter does not include an anti-drain back valve, it is best suited for applications where this feature is not required.
