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

This is a set of four forged pistons from JE Pistons, specifically designed for the Honda H22 engine. These pistons feature a 9.00:1 compression ratio, a 3.425-inch bore, and an inverted dome/dish design, making them a solid choice for building a performance-oriented H22. JE Pistons has been making forged pistons for over 75 years, and they engineer and machine these right here in the USA using 2618 aluminum, which offers the high tensile strength needed for demanding engine builds.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves 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 comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have everything you need to get started on your build.

When you're putting together a performance engine, the pistons are a critical component. These JE Pistons are built for durability and performance, proven in various racing applications. Remember 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.
