Product Details

Bosch Workshop Oil Filters are part of the Bosch Workshop Oil Filter line, a range focused on engine protection and consistent oil filtration for workshop service use. Part number 72165WS is a spin-on/canister oil filter with cellulose paper filtering material, a nitrile gasket, and a bypass relief valve to support oil circulation under restricted-flow conditions. The anti-drain back valve helps reduce dry starts by keeping oil in the filter when the engine is off.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Engine wear caused by circulating dirt and debris
• Oil drain-back after shutdown that can contribute to dry starts
• Restricted oil flow during cold starts or high-load operation
• Contaminant buildup in service intervals
• Premature engine damage from inadequate filtration

Installation Notes

Verify the 3/4-16 thread size, filter height, and outside diameter before installation. Replace the filter during routine oil service and confirm the gasket seats cleanly on the mounting surface. Compatible With 1985-1993 Mercedes-Benz 190E, 1986-1993 Mercedes-Benz 300E, 1988-1993 Mercedes-Benz 300TE, 1988-1991 Mercedes-Benz 300SE, 1988-1991 Mercedes-Benz 300SEL, 1987-1989 Mercedes-Benz 260E, and 1988-1989 Mercedes-Benz 300CE.

Quality Assurance
