Mitsubishi EVO 4-9 4G63 ZRP Forged Pistons EW10J4RS 0L C20 is manufactured fromThe Mitsubishi 4G63 EVO 4 9 pistons are developed for mild to high tuning, mainly for road or club race cars that want to develop their engine for high mileage and or street use. Designed by ZRP engineers and manufactured in Germany from 4032 (T6) high silicon, low expansion alloy. This allows the engine builder to run a closer piston to bore clearance thus producing a better seal. This minimizes the slapping noise during cold start, common place
