JE Pistons Honda K20A Max Dome 86.25mm Bore 12.4 Dome Volume Piston Kit (Set of 4 Pistons)

Forged from 2618 aluminum, these JE Pistons are built to handle the high stresses of performance Honda K20A engines. The 86.25mm bore size and 12.4cc dome volume are specific to this kit, designed to achieve a 12.50:1 compression ratio when installed in the appropriate K20A application. This is a critical component for anyone rebuilding or significantly upgrading their K-series engine for racing or high-performance street use.

JE Pistons brings over 75 years of experience to the table, and these pistons are a testament to that. They feature a proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width and a shorter wrist pin to minimize friction and save weight. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear, which can also quiet down the engine operation.

This kit includes everything you need to get these pistons installed: the set of four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Every component is manufactured 100% in the USA, ensuring a high level of quality control and material integrity for demanding performance builds. Remember, these pistons are not CARB approved and cannot be shipped to California.
