JE Pistons Honda K20A Max Dome 86mm Bore 12.4 Dome Volume Piston Kit (Set of 4 Pistons)

If you're rebuilding the top end of your Honda K20A engine for serious performance, a strong set of pistons is where you start. This JE Pistons Max Dome Piston Kit is built for demanding applications where durability and optimized power are critical. These aren't just generic pistons; they're specifically designed for the K20A engine to give you the best combination of strength and performance.

Crafted from 2618 aluminum right here in the USA, these pistons have the high tensile strength needed to handle the pressures of high-performance builds. JE Pistons uses a proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, contributing to better power output and longer life. Depending on the specific application, you might also find an accumulator groove to improve ring seal and a skirt coating to further cut down on friction and noise. This kit includes everything you need to get started: the four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

This kit is designed for a specific 86mm bore and features a 12.4cc dome volume, which is crucial for achieving a desired compression ratio, often around 12.5:1 for this setup. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
