Detailed Product Description

The Bosch 72237WS engine oil filter features a spin-on design that simplifies replacement while ensuring a secure fit with its 3/4-16 thread size. The cellulose paper filter media effectively traps contaminants down to 30 microns, helping to protect engine components from wear caused by dirt and debris. The inclusion of an anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing dry starts and improving engine longevity. The nitrile gasket provides a tight seal to prevent leaks under normal operating conditions. With a burst pressure rating of 200 PSI, this filter is built to withstand typical engine oil system pressures without failure.
