Wiseco Acura 4v DOME +5cc STRUTTED 81.5MM Piston Kit

This kit gets you four forged pistons, complete with precision ring grooves, anti-detonation features, and a special ArmorGlide skirt coating. These pistons are built for demanding performance applications, specifically designed for Honda B16A engines with an 81.50 mm bore. The dome design adds +5cc volume, and the strutted construction means they're built tough for racing and severe duty use.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. The machining is precise, including the crown and the ring grooves, which are designed for better ring seal and improved performance. The ArmorGlide coating on the skirts isn't just for looks; it helps reduce friction, resist seizure, and makes for quieter operation, all while handling heavy to severe duty performance builds. Forced pin oiling is also incorporated to ensure proper lubrication where it's needed most.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Honda B16A engine and need pistons that can handle serious stress, this Wiseco kit is a solid option.
