ArmorPlating piston coating – Reduces ill effects of high-heat in turbocharged sport-compact pistons. Applied only to the critical areas of the piston, Wisecos ArmorPlating reduces the effects on the dome from detonation. This special coating also helps reduce piston crown temperatures by 20C on average. Provides a hard, smooth surface for the rings and prevents micro-welding in the ring grooves.
