MAHLE Motorsport Subaru Forged PowerPak and PowerPak+ piston kits offer superior reliability and performance, letting you take performance to the next level. Subaru pistons are designed by our Motorsport division with 4032 or 2618 alloy. PowerPak Plus pistons include a hard anodized top ring groove for extreme duty applications. From 2.0L EJ20, 2.2L Stroker, or the FA20 Turbo the best engine builders and drivers make no compromises, and they trust MAHLE Motorsport.
Slipper Skirt Style Forgings: strong, lightweight, low drag forging superior to the traditional full round design.
Phosphate Coating: helps prevent microwelding in the ring grooves and pin galling.
Grafal® Anti-Friction Skirt Coating: reduces drag, scuffing, friction, cylinder bore wear, and reduces piston noise.
Hard Anodized Top Ring Grooves (PowerPak+ Piston Kits): extra protection against ring groove microwelding for extreme duty applications.
4032 or 2618 Aluminum Alloy: whether building a street engine or an all out race engine, both 4032 and 2618 alloys are available depending on the application.
