JE Pistons ACURA RSX K20A2 KIT Set of 4 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. Specifically designed for the Acura RSX K20A2 engine, this set of four pistons is engineered to handle the stresses of performance builds, whether you're pushing your car on the track or the street. The 2618 aluminum alloy offers high tensile strength, crucial for maintaining integrity under extreme operating conditions.

JE Pistons incorporates several design features to optimize performance and durability. The proprietary Forged Side Relief (FSR) design helps minimize friction and power loss by reducing skirt width, while also saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also feature 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 comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for a proper installation. Each piston is machined 100% in the USA, reflecting JE Pistons' commitment to quality and performance proven over decades of racing experience. Please note that this kit is not CARB approved and cannot be shipped to California.
