If you're rebuilding the engine in your Honda K20 or K24 for serious performance, a strong set of pistons is where you start. This single forged piston from JE Pistons is built to handle the demands of high-output builds. It features an 89mm bore and a 9.0:1 compression ratio, making it a solid choice for boosted or naturally aspirated setups where durability and consistent power are key.

JE Pistons has been making performance pistons for a long time, and this one is forged in the USA from 2618 aluminum. This material offers high tensile strength, which is exactly what you need when you're pushing an engine hard. They also use a proprietary Forged Side Relief (FSR) design that helps reduce friction and skirt wear, and some applications include a skirt coating to further minimize friction and noise. This piston is designed specifically for the K-series engine to optimize its performance and longevity.

This piston comes ready to install with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
