JE Pistons HOND B VTEC 84.5 KIT Set of 4 Pistons

This JE Pistons kit gives you a complete set of four forged pistons, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings. These pistons are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines built for demanding performance applications. They are specifically designed for the Honda B Series VTEC engine, with a bore size of 3.327 inches, to provide an optimized combination of performance and durability.

JE Pistons has incorporated their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also include a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

This set is designed for enthusiasts looking to build a high-performance Honda B Series engine. The 12.50:1 compression ratio is suitable for naturally aspirated builds or those using forced induction where tuning can manage the higher compression. Remember, this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
