What This Oil Filter Helps Address

Installation Notes and Tips

Verify the 13/16-16 thread size, filter height, and outside diameter before installation. Confirm the vehicle’s oil filter location and service access, then lubricate the gasket before tightening to the manufacturer’s specified torque. This Bosch 72235WS is a spin-on oil filter, so a clean sealing surface is important for proper fit and leak prevention.
