Mahle MS PowerPak Plus Forged Pistons for Subaru WRX EJ255 99.75mm -14.1 cc 9.7:1
The Mahle PowerPak Plus 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 file fit 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.
