JE Pistons Honda L15B Turbo 73mm Bore 9.5:1 CR -13.4cc Dome Piston Set - Set of 4

If you're building a high-performance Honda L15B turbo engine, a strong set of pistons is where it all starts. This set from JE Pistons is designed specifically for these turbocharged applications, offering the durability and performance needed when you're pushing the limits. They are forged from 2618 aluminum, a material known for its high tensile strength, which is crucial for handling the increased pressures and temperatures found in a boosted engine.

JE Pistons brings over 75 years of experience to the table with these components, and they're made entirely in the USA. You'll find their proprietary Forged Side Relief (FSR) design, which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear, while also quieting down the engine operation.

This set includes everything you need to get your engine rebuilt: the four pistons themselves, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. It's important to note that these pistons are not CARB approved and cannot be shipped to California.
