Tomei 2.2L/2.3L Forged Pistons for 4G63 Mitsubishi Evo 4-9
At the core of the engine, pistons convert combustion gas into power. Choose Tomei or CP pistons with 85.5mm or 86mm bore for the 4G63 Evo 4-9 engine. Exclusive forged material is lightweight, preventing excessive machining and strength reduction. The 3D profile ensures smooth movement with optimal clearance and an oval barrel shape for thermal expansion.
