These pistons are recommended for any high performance engine build, as they offer unparalleled strength and longevity.

Features:

• Complete Kit incl. Cylinder
• OEM fitment and wear characteristics
• Quite piston operation
• Ideal compression ratio and dish shape
• Durable forged pistons
• Lightweight piston design
• High strength German steel wrist pins for high horsepower support
• Propriety Mahle low-expansion 142P alloy
• Tight ring to piston groove clearances to reduce blow-by
• Hard anodized ring lands to avoid micro-welding

specifications:

• Bore: 102,00 mm
  
• Compression: 9,3:1
• Pin: 23mm

To maximize power output, the clearances between the rings and piston have been brought in very tightly to reduce blow by. This is achieved by hard anodizing the top ring lands, which prevents micro welding which could be caused otherwise.

Those cyliders (Liners) are only available on email request.

To maintain OEM-like wear characteristics, these pistons are coated with Mahle’s Grafal skirt coating. This coating reduces friction on the skirts, keeping them quiet and from wearing over time- extending piston life. The grey appearance of these pistons is due to a phosphate coating. Providing a lubricant film in the pin bores and ring grooves, this coating is essential for initial startup and break-in of the engine to prevent micro welding and galling. Features like these are what allow these pistons to last for thousands of miles, just like OEM units.
