MAHLE PowerPak Forged Piston Kit BMW

The MAHLE PowerPak Forged Piston Kit is a forged performance piston set from MAHLE Motorsport. It replaces the factory cast aluminum pistons in BMW engines. Forged pistons tolerate the heat, detonation and cylinder pressure of tuned, performance-oriented engines better than cast pistons. Engine builders also know the kit as a forged piston set, a performance piston kit or an engine rebuild piston and ring kit.

Key Features:

• Forged aluminum pistons for performance applications, made from high-strength alloys such as 2618 or 4032 depending on the application
• Fully machined crown and lightweight slipper skirt design
• Phosphate dry lubricant coating helps protect against ring micro-welding and pin galling during startup and break-in
• Proprietary GRAFAL anti-friction skirt coating reduces drag, scuffing, wear and piston noise
• Hard anodized top ring groove on applicable kits protects against micro-welding
• Pin bores finished with CNC machining, and pistons are hand deburred
• High-strength steel piston pins and race-proven round wire locks
• Low-drag performance ring set

MAHLE Motorsport designed the PowerPak program as a stock-available option for performance enthusiasts and engine builders. It gives a durable, proven upgrade over OE pistons for BMW builds with increased power output.
