Technical Details and Performance Features
The Wix 51820 engine oil filter utilizes cellulose media with a 25-micron rating to capture contaminants effectively while maintaining oil flow. The anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during startup. Its heavy-duty classification and a burst pressure of 390 psi ensure the filter withstands high-pressure conditions without failure. The bypass relief valve is set at 30 psi, allowing oil to bypass the filter element if it becomes clogged, protecting the engine from oil starvation. The spin-on lube filter design with a 1-12 thread size simplifies replacement and ensures a secure fit.
