DESCRIPTION
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!
- Slipper Skirt Style Forgings: strong, lightweight, low drag forging superior to the traditional full round design.
- Phosphate Coating: helps prevent microwelding in the ring grooves and pin galling.
-
Grafal® Anti-Friction Skirt Coating: reduces drag, scuffing, friction, cylinder bore wear, and reduces piston noise.
- Hard Anodized Top Ring Grooves: extra protection against ring groove microwelding for extreme duty applications.
- Heavy Duty Pins: thick walled H13 tool steel pins for strength.
- Rod: 144mm
