Wiseco Honda L15B7 -14.65cc 2.874 X 1.125 R-Dome Piston Kit

If you're building a high-performance Honda L15B7 engine, this Wiseco forged piston kit is designed to handle some serious punishment. These aren't your average pistons; they're built for heavy to severe duty race applications where reliability under extreme stress is critical. Wiseco machines these pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential when you're pushing an engine hard.

You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which helps maintain compression and prevent blow-by. They also come with an ArmorGlide skirt coating. This coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all important factors when you're aiming for maximum performance and longevity in a race build. The fully machined crown also means a clean, consistent combustion chamber shape.

This kit includes four pistons, each with a 73.00 mm bore and a 28.60 mm compression height, and uses a 0.787-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious builders, these pistons are a solid choice for a robust L15B7 engine build.
