About this part

Product Details

Mahle OE oil ring expanders are a key component for rebuilding or refreshing an engine. These expanders work with your oil control rings to ensure they maintain proper tension against the cylinder wall. This helps them effectively scrape excess oil from the cylinder, preventing it from entering the combustion chamber and causing issues like oil burning or fouled spark plugs.

This is a bulk pack containing 48 individual oil ring expanders, designed for engine builders or shops working on multiple engines. They are made to Mahle's OE specifications, meaning they meet the same standards as the parts originally installed on the vehicle. The 4.390-inch diameter and 3/16-inch width are common dimensions for many applications, but it's always best to confirm your specific engine's requirements.

Please note that this part is not CARB approved and cannot be shipped to California addresses.
