Mahle OE Ford 4.6L 90L77++A6 .50MM with Pin Romeo Engine Piston Set (Set of 8)

Mahle is one of the largest OE piston manufacturers globally, known for making parts that meet original equipment specifications. This piston set is built for Ford 4.6L Romeo engines and is 0.50mm undersize, meaning it's designed for engines that have been bored out to accommodate this size. These pistons are ready to install right out of the box, coming with the piston rings already mounted, along with the necessary pins and clips for your convenience during your engine rebuild.

These pistons feature compensated ring grooves, which help ensure proper ring loading and effective oil control. They also have an expansion-controlled design. This means they're built with small fitting clearances, helping to reduce engine noise, wear, and emissions while improving overall oil management. This set is designed to fit a range of Ford, Lincoln, and Mercury vehicles from the mid-to-late 1990s, including models like the Crown Victoria, Expedition, and F-150.
