Pistons are manufactured in Argentina with technology transferred from European manufacturers. SUPERTECH pistons are manufactured from extruded high silicon, enhanced 4032 alloy (with additional Cu, Ni & Mg) that has low thermal expansion, excellent wear resistance and higher thermal conductivity. Our pistons with this alloy have withstood up to 42psi of turbo boost, with alcohol, without any problems. A 2 or 3 forging steps process yields a fine structural grain oriented in fibers in the same direction of the stresses. Piston P/N: P4-H81-P7 P4-H81-P6 / P4-H81-N2 / P4-H815-P6 / P4-H815-P7 / P4-H815-N2 / P4-H82-N2 / P4-H82-P6 / P4-H82-P7 / P4-H83-P6 / P4-H84-N10 / P4-H84-p1 / P4-H84-P5
