Diameter/Compression Ratio

This is a set of extremely high quality Mahle PowerPack pistons for the S65 engine. Mahle Powerpack pistons are extremely high quality pieces which provide improvements in strength over OEM pistons without some of the sacrifices sometimes found in other forged pistons. Mahle Powerpack pistons are precision forged from 4032 alloy, a low expenasion rate aluminum. They all feature forged side reliefs, reducing the weight of the overall package. They also use slipper skirt designs, reducing friction and further reducing weight. Mahle PowerPack pistons feature ultra flat ring grooves, which promote excellent ring seal and most importantly reduce the chances of micro-welding during break in. This piston set is available in an Alusil version and a custom ordered sleeved block version with Grafal skirt coating.

Mahle PowerPack Pistons are an excellent choice for those looking for increases in strength while maintaining a lightweight piston with oem fit and finish.
