JE Pistons Honda B16A1/A2/A3 83mm Bore -3.3cc Dome 9.0:1 CR Kit - Set of 4 Pistons

If you're rebuilding the engine in your Honda B16A1, A2, or A3 and looking for a solid set of pistons to handle more power, this JE Pistons kit is a great place to start. These aren't just off-the-shelf parts; JE Pistons has been making forged performance pistons for over 75 years, and they build these specifically for your B-series engine. They're designed to give you the durability and performance you need when you're pushing the engine hard.

What makes these pistons stand out is the material and the design. They're forged from 2618 aluminum right here in the USA, which gives them the high tensile strength needed for demanding applications. JE uses a proprietary Forged Side Relief (FSR) design that helps reduce friction and skirt wear, saving a little weight and improving how the piston moves in the cylinder. Depending on the specific application, you might also find an accumulator groove to help manage combustion pressure and a skirt coating to further cut down on friction and noise. This kit includes everything you need to get them installed: the four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

This set is designed for an 83mm bore with a 9.0:1 compression ratio, giving you a good balance for street performance or track use. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
