The Wiseco K567M84AP Professional Series forged racing piston set is engineered for serious enthusiasts and professional racers seeking maximum performance and durability. Crafted from premium 2618 aluminum in the USA, these pistons offer enhanced tensile strength to withstand the rigors of heavy-duty racing applications. Each piston features precision-machined ring grooves, an anti-detonation groove, and additional seal enhancements to optimize combustion efficiency and reduce the risk of engine knocking. The ArmorGlide skirt coating provides excellent seizure resistance, friction reduction, and quieter operation, contributing to prolonged engine life and consistent power output. Designed specifically for Honda B16A engines with an 84.00 mm bore and a 30.00 mm compression height, these pistons include a 0.827-inch pin diameter and are supplied as a set of four, making them ideal for rebuilds or performance upgrades. Fully machined crowns ensure precise fitment, while forced pin oiling ensures reliable lubrication during high-stress conditions. These pistons are built to handle severe duty applications, providing the strength and reliability necessary for competitive racing or high-performance street driving. As a product that requires carb acknowledgment, they are suitable for use in non-CARB-compliant environments and are not approved for emissions certification, making them perfect for race builds and custom projects. With Wiseco's commitment to quality and innovation, the K567M84AP pistons deliver exceptional performance, durability, and confidence for your engine rebuild or upgrade.
