Wiseco Forged Pistons

For all VW/Audi 1.8T 20V turbo engines, these Wiseco pistons are produced in-house from dedicated forgings. This results in a very light weight piston that retains high strength attributes. This optimal design features specially designed valve pockets, complex dome and crown shapes, steel nitride/napier rings and optimized skirt profiles. This piston set is manufactured standard with Wiseco's ArmorGlide coating material. ArmorGlide coating reduces friction and pistons noise and frees up horsepower usually lost through these friction surfaces. For use with 20mm wrist pin connecting rods.
