JE Pistons Acura K24/K20 Kit (Set of 4 Pistons)

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set of four pistons is specifically designed for Acura K24 and K20 engines, offering a 3.465-inch bore and a 12.10:1 compression ratio with a dome design. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to ensure the ultimate combination of durability and performance for your build.

The proprietary Forged Side Relief (FSR) design is a notable feature, minimizing friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce pressure from combustion gases, leading to better ring seal and consistent power. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, making it a comprehensive solution for your engine rebuild. Engineered and forged in the USA, these pistons are a solid choice for anyone looking to push the limits of their K-series engine, whether for track use or spirited driving.
