Mahle PowerPak+ drop-in pistons for the Audi 2.5T DAZA & DNWA engine.
These pistons are made from Mahles proprietary M142P material. It is a low expansion aluminum alloy similar to 4032 but with improved strength characteristics. At elevated temperatures it offers approximately 15% improvement in tensile / yield strength.
These pistons are compatible with both the factory APS cylinder walls AND aftermarket iron sleeves!
