Technical Details and Performance
The Wix 51749 oil filter utilizes cellulose media to capture particles down to 5 microns, helping to maintain engine cleanliness and protect critical components. Its beta ratio of 2/10=5/14 indicates effective filtration efficiency at different particle sizes. The filter’s burst pressure rating of 300 psi ensures structural integrity under high-pressure conditions common in heavy-duty engines. With a flow rate of 1.75 gallons per minute, it supports adequate oil flow to maintain lubrication and cooling.
The filter’s spin-on design with a 1 3/8-16 thread size allows for straightforward installation and removal. The closed inner diameter top and dimensions (height 9.748 inches, outer diameter 4.661 inches) are engineered to fit specific engine configurations. Note that this filter does not include an anti-drain back valve or bypass relief valve, which should be considered when matching to compatible vehicles.

It is compatible with various makes and models that specify a 1 3/8-16 thread size and require a 5-micron cellulose media filter with the given dimensions. Always verify fitment with your vehicle’s manufacturer specifications or consult a professional mechanic to ensure compatibility.
Common Issues Addressed by Wix 51749
- Prevents engine wear by filtering out fine contaminants

Installation Notes and Tips
When installing the Wix 51749 oil filter, ensure the engine is cool and the oil system is depressurized. Apply a thin layer of clean engine oil to the gasket before threading the filter to improve sealing and ease removal. Tighten the filter according to manufacturer torque specifications to avoid leaks or damage. Since this filter lacks an anti-drain back valve, consider the oil system design to prevent dry starts.
