JE Pistons HONDA B18C1 12.5 KIT Set of 4 Pistons

Forged from 2618 aluminum, these JE Pistons are built to handle the demands of a high-performance Honda B18C1 engine. This set of four pistons is designed for a 3.209-inch bore and features a 12.50:1 compression ratio, making them suitable for builds aiming for significant power gains. JE Pistons brings over 75 years of experience to the table, ensuring that each piston is engineered specifically for the B18C1 application to offer a balance of durability and performance.

The proprietary Forged Side Relief (FSR) design is a key feature, minimizing friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also helps save weight. Depending on the specific application, these pistons may include an accumulator groove to manage combustion gas pressure, which helps reduce ring flutter and improve ring seal for consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life. Every component is forged and machined in the USA, ensuring a high standard of manufacturing for critical engine parts.

This kit includes everything you need to get your engine rebuilt with these high-performance pistons: the four pistons themselves, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. It's important to note 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 procedures.
