What does '.020 undersize' mean for these pistons?

This means the pistons are manufactured to be 0.020 inches smaller in diameter than the original factory specification. This size is used when the engine cylinders have been bored out during an engine rebuild to ensure a proper fit and seal.

What is included in this piston and ring set?

This set comes with 8 cast pistons, each with the piston rings already mounted. It also includes the necessary wrist pins and retaining clips, providing a convenient, ready-to-install package for your engine build.

Are these pistons suitable for all 4.6L Ford engines?

No, this specific set is designed for the 4.6L PI (Performance Improved) SOHC (Single Overhead Cam) engines found in certain Ford and Mercury vehicles from 1999-2005. Always verify fitment for your specific vehicle and engine code.

Product Details

If you're rebuilding the engine in your Ford 4.6L PI SOHC, this Mahle OE piston and ring set is a solid choice. These pistons are made to the original equipment specifications, meaning they'll perform just like the ones your engine came with from the factory. This particular set is .020 inch undersize, which is crucial for engines that have been bored out during a rebuild to clean up cylinder walls or account for wear.

Mahle is one of the biggest original equipment piston manufacturers in the world, and these pistons reflect that experience. They feature compensated ring grooves, which help ensure the piston rings are loaded correctly for good oil control and sealing. The expansion-controlled design means they're built with tight clearances, helping to reduce engine noise and wear while improving oil control and emissions. You get a complete set with the pistons, rings already mounted, plus the necessary pins and clips, so you can get right to work on your engine build.

This set is designed for a wide range of Ford and Mercury vehicles from the late 90s and early 2000s, including popular models like the Ford F-150, Crown Victoria, and Mustang. It's important to note that these are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for detailed installation procedures and specifications.
