JE Pistons HONDA H22 9:1 KIT Set of 4 Pistons

These JE Pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushed to their limits. This specific kit is designed for the Honda H22 engine and features an inverted dome/dish design, resulting in a 9.00:1 compression ratio. This compression level is a popular choice for builds that aim for improved performance without sacrificing too much drivability or requiring extremely high octane fuel.

JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA. They utilize a proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. 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 build. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
