JE Pistons Honda B16A1/A2/A3 83.0mm Bore 8.0:1 CR 10.8cc Dome Piston Kit (Set of 4 Pistons)

If you're rebuilding the heart of your Honda B16A1, A2, or A3 engine for serious performance, this JE Pistons forged piston kit is a solid choice. These pistons are specifically made for your B-series engine, featuring an 83.0mm bore and an 8.0:1 compression ratio with a 10.8cc inverted dome. This setup is designed to handle the demands of high-performance applications, offering a good balance for boosted or high-compression builds.

JE Pistons has been making forged pistons for over 75 years, and these are forged, machined, and assembled 100% in the USA using 2618 aluminum. This material choice gives them the high tensile strength needed for demanding engine builds. They also feature JE's proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to improve ring seal and a skirt coating to cut down on friction, wear, and engine noise.

This kit includes everything you need to get your pistons installed: four forged pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal installation, always refer to the manufacturer's detailed instructions.
