Reduces oil temperature. Lowers piston crown operating temperature. Applied at.0015 thick. Aids in increasing piston service life by reducing heat transfer to piston. ANODIZING RING GROOVE Limits micro welding of ring to groove in severe conditions. Produces a very hard surface for ring to rotate on. PISTON HEAD Creates barrier from corrosive fuels. Abradable skirt coating. Applied at skirt clearance thickness for an initial ZERO fit. Hones in it maintain oil wedge for a perfect fit to cylinder greatly reducing piston rock. Shock loads and degradation in piston/rod/bearing assembly is reduced. ANTI FRICTION COATING Excellent protection from dry start up wear. Decreases engine noise. Applied to.0005 thick per side.
