Technical Details and Compatibility

The PG111EX engine oil filter features a synthetic blend media that effectively traps contaminants down to 25 microns, helping to protect engine components from wear. The anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing dry starts and engine wear. The bypass relief valve activates between 20±2.9 to 21-25 psi to ensure continuous oil flow even if the filter becomes clogged. With a flow rate of 7.93 gallons per minute, this filter supports efficient oil circulation.

Its silicone gasket, measuring 0.21 inches thick with an inside diameter of 2.51 inches and an outside diameter of 2.89 inches, ensures a secure seal to prevent leaks. The filter’s height is 3.44 inches, and it uses an M18x1.5p thread size for installation.

Installation Notes and Tips
