Overview

Upgrade your B58 3.0 L turbocharged engine with this complete high-performance forged piston and ring kit from MAHLE Motorsport. Designed as a direct-fit replacement for the factory pistons, this PowerPak kit delivers enhanced strength, reduced reciprocating mass, and improved durability — perfect for builds aiming to handle increased boost, higher power output, and extended track use.

Whether you’re building a high-power street/track engine or strengthening a B58 for more forced induction and tuning, this Mahle PowerPak kit provides the strength, reliability, and performance margin needed over stock cast pistons. The forged 2618 alloy and carefully engineered features make it a trusted choice for enthusiasts and professional builders alike.
