Key Features:

• OE-Driven Engineering: Developed to meet or exceed original equipment manufacturer requirements for fit, form, and function
• Friction Reduction: Advanced ring geometry and surface treatments minimize friction between the ring and cylinder wall, improving efficiency and reducing wear
• Reduced Ring Mass: Lightweight ring design lowers inertia forces at high RPM, contributing to improved engine response and durability
• Minimized Oil Consumption: Precision oil control ring design limits oil passage into the combustion chamber, keeping oil consumption in check
• Extended Service Life: High-quality materials and coatings provide long-lasting sealing performance under demanding operating conditions
• Industry-Leading Technology: MAHLE applies cutting-edge piston ring technology developed through decades of OE motorsport and production engine experience
