JE Pistons Honda B16A1/A2/A3 82.0mm Bore 8.0:1 CR -9.5cc Dome Piston Kit (Set of 4 Pistons)

If you're rebuilding the engine in your Honda B16A1, A2, or A3, this set of four forged pistons from JE Pistons is a solid choice for high-performance applications. These pistons are specifically made for an 82.0mm bore size and feature an 8.0:1 compression ratio with a -9.5cc inverted dome. JE Pistons has been making forged pistons for over 75 years, and these are engineered and machined 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 JE's proprietary Forged Side Relief (FSR) design. This helps minimize friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, which improves ring seal and keeps power consistent. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise. This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have everything needed to get these pistons installed.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific engine applications to optimize performance and durability, making them a popular choice for serious engine builds.
