Construction & Design:

Mahle OE pistons are crafted from high-grade aluminum alloy, optimized for strength, heat dissipation, and lightweight performance. The pistons feature precision-machined surfaces and ring grooves engineered to maintain optimal ring seal and oil control under demanding conditions. The expansion-controlled design accounts for thermal growth, allowing tight clearances that minimize piston slap and reduce mechanical noise. This meticulous engineering helps extend engine life and maintain smooth operation.

Each piston is balanced and inspected to meet strict OE tolerances, ensuring consistent performance and reliability. The inclusion of pre-mounted rings and hardware simplifies assembly and reduces the risk of installation errors.
