SUPERTECH K20A 86.5MM BORE PISTON Compression:12:01 360CFM CNC cylinder head equippedSUPERTECH K20A 86. 5MM BORE 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
