JE Pistons Honda B Series 82mm Bore 4.5cc Dome - Set of 4 Pistons SPECIAL ORDER

If you're rebuilding the engine in your Honda B Series vehicle for serious performance, a set of forged pistons like these from JE Pistons is a critical component. These aren't your average pistons; they're built from the ground up to handle the stresses of high-performance applications, whether you're hitting the track or pushing your street car to its limits. JE Pistons has been making these kinds of parts for over 75 years, and they're forged and machined right here in the USA using 2618 aluminum, which gives them the high tensile strength needed for demanding builds.

What sets these pistons apart is their design, tailored specifically for the Honda B Series engine. They feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, saving weight and potentially improving power. The 4.5cc dome shape is designed to achieve an 11.50:1 compression ratio when paired with the correct cylinder head and gasket combination, giving you a noticeable bump in power and throttle response. You'll also find an accumulator groove, which helps reduce combustion gas pressure for better ring seal, and depending on the specific application, a skirt coating to further cut down on friction and noise. This set 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 engine build.

Because these are special order pistons, please be aware that they are not CARB approved and cannot be shipped to California. It's always a good idea to double-check your engine's specific requirements and consult with your engine builder to ensure these pistons are the right fit for your build goals.
