Mahle PowerPack S52 B32 86.6MM Bore, 11.3:1 CR, 89.6mm Stroke

This is a set of extremely high quality Mahle PowerPack pistons for the S52 (1996-1999) 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. Every set of Mahle PowerPack pistons comes with their exclusive Grafal skirt coating, which is not only anti-friction but also offers impact absorbing qualities, reducing piston noise and decreasing stresses in the piston skirt.nnMahle PowerPack Pistons are an excellent choice for those looking for increases in strength while maintaining a lightweight piston with oem fit and finish. They have 22mm wrist pins so they will require a set of rods with 22mm pins to match.nnFeatures:nn86.6mm Bore, 89.6mm stroke.nUse with 135mm Rodn11.3:1 Compression rationCOMPLETE WITH RINGS AND PINS
