Product Description
The MAHLE OC 47 Oil Filter is a premium, spin-on filter cartridge engineered to provide maximum filtration efficiency while maintaining optimal oil flow for older, high-revving internal combustion engines. MAHLE's filtration technology utilizes high-grade, resin-impregnated filter paper that captures microscopic contaminants—such as metal wear particles, carbon deposits, and soot—that would otherwise circulate and cause premature wear to engine bearings and cylinder walls. This filter features a high-quality anti-drain back valve, which ensures oil remains in the upper engine galleries during shutdown, providing immediate lubrication upon the next cold start.

⚠️ Installation & Maintenance Tip:When installing the OC 47, always perform these two steps to ensure a leak-free seal:
- Pre-Lubrication: Take a small amount of clean engine oil and coat the rubber gasket on the top of the new filter. This allows the seal to seat evenly against the engine block without binding or twisting.
- Hand Tighten Only: Never use an oil filter wrench to tighten the filter. After the gasket makes contact with the block, tighten it by hand another 3/4 to 1 full turn. Over-tightening with a tool can damage the seal or make it impossible to remove during the next service interval.
- Check the Old Seal: Always ensure the old rubber gasket from the previous filter did not stay stuck to the engine block. If you accidentally double-gasket the new filter, it will spray pressurized oil everywhere as soon as you start the engine.
