Product Details

*For use with 20mm wrist pin connecting rods*

Mahle Pistons:
For all VW/Audi 1.8T 20V turbo engines.  Mahle has responded to the demanding requirements for today's performance pistons.  Higher power demands have risen thermal loads, high engine speeds have increased inertia load, ignition pressure stress has increased through direct fuel injection and turbocharging.  Utilizing OE experience and innovative concepts, Mahle has continually adapted existing piston designs to combat challenges of aftermarket demands.  Mahle pistons utilize weight optimized aluminum pistons manufactured from high-temperature resistant aluminum silicon alloy. This alloy along with Mahle's refined design and production technology enable an ideal combination producing pistons with low weight and high load-bearing capacity. For use with 20mm wrist pin connecting rods such as Integrated Engineering h beam 144X20 or Integrated Engineering Tuscan I beam 144X20 connecting rods.

GRAFAL Piston Coating:
Mahle pistons are treated with their own coating known as GRAFAL. GRAFAL skirt coating greatly reduces the skirt to wall surface friction and increases scuffing resistance.  Another advantage of the GRAFAL coated pistons is they enable a closer fitting clearance that gives significantly lower engine noise in conjunction with complex piston forms.

Product Features:

  • Included Mahle piston rings, wire locks, and wrist pins
  • Included Mahle's GRAFAL piston coating
  • No dish deburring or preparation needed
  • Individually prepared and inspected

*81.5mm Bore Size Requires Machine Work*
