JE Pistons Honda L15B Turbo 73mm Bore 10.3:1 CR -9.6cc Dome Piston Single Piston

Forged from 2618 aluminum, this JE Pistons single piston is built for demanding performance applications, especially in boosted engines like the Honda L15B7 Turbo. The material choice here is key; 2618 aluminum offers high tensile strength, which is exactly what you need when you're pushing more boost and heat through your engine. This piston is specifically designed for the L15B7 Turbo, featuring a 73mm bore and a 10.3:1 compression ratio with a -9.6cc inverted dome dish. This design helps optimize combustion for boosted setups, aiming for a good balance of power and reliability.

JE Pistons machines these components 100% in the USA, incorporating their proprietary Forged Side Relief (FSR) design. This means the piston skirt is narrower and the wrist pin is shorter, which reduces friction and weight while still maintaining solid support. Depending on the specific application, you might also find a skirt coating to further cut down on friction and noise, along with an accumulator groove designed to improve ring seal and prevent flutter under high combustion pressures. This piston comes ready to install with high-quality wrist pins, locks, and JE Pro Seal premium piston rings.
