Tomei 2.3L Forged Pistons for 4B11 Mitsubishi Evo X
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 4B11T Evo X engine. Made from exclusive forged material, these pistons are lightweight, reducing the need for excessive machining and preventing strength reduction. The 3D profile ensures smooth movement with optimal clearance and an oval barrel shape designed for thermal expansion.
