Description
Icon Forged Pistons are forged from 4032 alloy. With an 11% silicon content 4032 alloy controls the thermal expansion so a tighter piston to wall clearance may be used over a 2618 alloy. The additional silicon also decreases the wear on the skirts and pin bores. This material makes these Icon Pistons ideal for street and mild boosted applications
