What does '.50MM' mean for these pistons?

The '.50MM' indicates that these pistons are undersized by half a millimeter. This means they are intended for use in engine cylinders that have been bored out by that amount, typically during an engine rebuild to clean up wear or damage.

Do these pistons come with everything needed for installation?

Yes, this set of four pistons comes with the piston rings already mounted, as well as the necessary wrist pins and clips. This makes the installation process more convenient for engine builders.

Are these pistons suitable for all 2.2L ECOTEC engines?

This piston set is specifically designed for the 2.2L ECOTEC engines used in many Chevrolet, Pontiac, and Saturn vehicles between the 2002 and 2008 model years. It's important to verify fitment for your specific vehicle's year, make, and model.

Product Details

These Mahle OE pistons are .50MM undersize, meaning they are designed to fit cylinders that have been bored out by 0.020 inches. They feature compensated ring grooves, which help ensure the piston rings load correctly and maintain proper oil control. This is a critical detail for keeping oil out of the combustion chamber and maintaining good compression. The expansion-controlled design also means they fit with smaller clearances, which helps reduce engine noise and wear, ultimately improving emissions and oil control.

Mahle is a major OE supplier for many manufacturers, so you're getting pistons built to the same standards as what originally came in your GM 2.2L ECOTEC engine. This set of four pistons comes with the piston rings already mounted, along with the wrist pins and clips, making installation more straightforward for the engine builder. They are designed for a range of Chevrolet, Pontiac, and Saturn vehicles from the early to mid-2000s, offering a well-built option for engine rebuilds.
