JE Pistons Honda K-Series 89.00mm Bore 12.5:1 CR 1.176 CD Dome Piston Kit - Set of 4

If you're rebuilding the engine in your Honda K-Series for serious performance, a set of high-strength forged pistons is a critical component. This kit from JE Pistons is designed to handle the increased stress and heat that comes with a performance build, offering a significant upgrade over stock cast pistons. They are specifically made for the K-Series engine to ensure optimized performance and durability.

JE Pistons uses a proprietary forging design called FSR (Forged Side Relief) which helps reduce friction and skirt wear, saving weight and potentially improving power. These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for high-demand applications like track use or boosted engines. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power output. Some applications also include a skirt coating to further reduce friction and noise.

This kit includes everything you need to get your engine rebuilt: four pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
