JE Pistons MITSU EVO VII-IX KIT Set of 4 Pistons

If you're rebuilding the engine for your Mitsubishi Lancer Evolution VII, VIII, or IX, these JE Pistons are a solid choice. They're forged in the USA using 2618 aluminum, which gives them the strong tensile strength needed for high-demand performance applications. JE Pistons has been making forged racing pistons for over 75 years, and they design these specifically for the 4G63 engine to give you the best combination of durability and performance.

These pistons feature JE's proprietary Forged Side Relief (FSR) design. This helps minimize friction and power loss by reducing skirt width, and it saves a little weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure for better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear, while also cutting down on operating noise. You'll get a complete set with high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for the 4G63 engine with a 3.366 inch bore and include a 0.866 inch wrist pin. This kit is for a set of 4 pistons.
