JE Pistons Honda L15B Turbo 73.5mm Bore 10.3:1 Compression Inverted Dome Piston Set (Part Number 357430)

Description

Upgrade your Honda L15B Turbo engine with the JE Pistons Part Number 357430, a premium forged piston set designed for high-performance applications. Crafted from high tensile strength 2618 aluminum in the USA, these pistons are engineered to withstand demanding conditions on the track or street. The set includes four pistons, each featuring a 73.5mm bore and a compression ratio of 10.3:1, optimized for enhanced power output and durability. The inverted dome design provides ideal combustion characteristics, contributing to improved efficiency and performance.
JE Pistons’ proprietary Forged Side Relief (FSR) forging minimizes friction and power loss by reducing skirt width and saving weight with a shorter wrist pin, leading to better throttle response and increased acceleration. The pistons incorporate an accumulator groove, depending on application, which helps reduce pressure from combustion gases, thereby reducing ring flutter and maintaining a consistent seal for steady power delivery.
To further reduce friction and wear, the pistons feature a skirt coating that diminishes operating noise, prolonging component life and ensuring smooth operation. Each piston is machined with precision and includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, all designed to work harmoniously for maximum performance. Made entirely in the USA, these pistons are a reliable choice for enthusiasts and racers seeking durability and performance in their engine build. Please note that these pistons are not CARB approved and require acknowledgment of this status during installation.
Whether you’re building a performance street engine or a race-ready setup, JE Pistons’ Honda L15B Turbo piston set offers the perfect blend of strength, weight savings, and optimized combustion chamber design, making it an essential upgrade for serious Honda enthusiasts.
