Forged Piston Kit "Flat Top" 87.5mm - C20XE

"Flat Top" Forged Piston Kit (3 ring) for Vauxhall C20XE engines.

Wössner pistons feature a unique Moly coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance than on another make of piston. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger than OE bore clearances. The crowns of the pistons are also mirror polished to better resist detonation on a high performance engine. Mirror polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns.

Includes all piston rings and gudgeon pins.

Spec:

OE Bore Size - 86mm

Available Bore Sizes - 87.5mm only
