JE Pistons Acura K20/K24 Max Dome 88mm Bore 12.5:1 Comp Ratio - Set of 4

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications, offering the high tensile strength needed for serious engine builds. They are specifically designed for Acura K20 and K24 engines, featuring an 88mm bore and a Max Dome design that results in a 12.5:1 compression ratio. This setup is ideal for naturally aspirated builds aiming for maximum power output.

JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA. They incorporate a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes four pistons, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, making it a comprehensive kit for rebuilding or upgrading your K-series engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
