Product Details and Specifications

The Bosch 72245WS oil filter features cellulose paper filter media that effectively traps contaminants while maintaining oil flow. Its spin-on design simplifies replacement and maintenance. The anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during startup. The bypass relief valve activates between 8 and 16 PSI to maintain oil circulation if the filter becomes clogged. With a burst pressure rating of 200 PSI, this filter withstands high-pressure conditions common in heavy-duty engines. The nitrile gasket ensures a secure seal to prevent leaks, and the 13/16-16 thread size matches OEM specifications for compatible Chevrolet Express 2500, GMC Savana 3500, and Hummer H1 models.
