Mahle PowerPak Piston
Kit: SUBARU
The Mahle PowerPak is a complete, race proven piston assembly kit.
It is composed of hand deburred, forged, performance coated pistons,
high quality steel pins, round wire locks and low drag performance
rings.
Performance coatings include a phosphate dry lubricant that is used to
protect against ring micro-welding and pin galling during initial
startup and break in. For added performance, MAHLE applies its
proprietary Grafel anti-friction coating to each piston skirt.
Piston Kit Features:
- Forged from 4032 high silicon low expansion aluminum alloy for
high strength and reduced piston to wall clearance.
- Radiused valve pockets.
- Forced pin oiling
- Precision pin fitting and easy to use round wire locks included
- 23mm high quality German steel wrist pins (123 grams)
