SUPERTECH K24 BLOCK / K20 HEAD 87.5MM BORE PISTON

SUPERTECH K24 BLOCK / K20 HEAD 87.5MM BORE FORGED PISTON Supertech Pistons are manufactured from extruded high silicone, enhanced 4032 alloy (with additional Cu, Ni & Mg) that had low thermal expansion, excellent wear resistance and higher thermal conductivity. Supertech Pistons, with this alloy, have withstood up to 42psi of boost, with alcohol, without any problems. A two or three step forging process yields a fine structural grain which are then submitted to several machining steps in state of the art CNC machines. Several heat treatments provide the piston with high tensile strength and evenly distributed hardness. Contact reduction grooves are standard, and pin bores are honed and reamed for precise fit. Wrist pins are constructed of cold extruded chromemoly steel for high strength and used with wire clip locks. Finally, the pistons receive a ‘phosphate dry lubricant’ coating to protect the rings against ‘micro-welding’ and enhance lubrication on the skirt/cylinder area. ~Rings Are Not Included   Application: Engine codes: K24A1 • K24A2 • K24A4 • K24A8 • K24Z3• K24Z7 K24 Vehicle Fitment: Accord 06-07 CM4-CM8 Accord 08-13 CP2/CS1 CR-V 02-06 RD4-RD9 TSX 04-08 CL9 Accord 03-05 Element 03-06
