Wiseco Acura 4v +2cc Dome Strutted 84.25mm Bore Piston Kit - Set of 4

These Wiseco pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the higher pressures and temperatures found in performance engine builds. The +2cc dome design is specifically shaped to work with certain cylinder head configurations, contributing to optimized combustion chamber volume and compression ratio for your engine. Each piston is machined in the USA, ensuring precise manufacturing for critical engine components.

Wiseco has incorporated several features to enhance durability and performance. The pistons include precision ring grooves, anti-detonation grooves, and additional ring seal features to ensure a tight seal between the piston and cylinder wall, which is vital for maintaining compression and preventing blow-by. The crown of each piston is fully machined for accuracy, and they are equipped with forced pin oiling to keep the wrist pin lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, while also contributing to quieter operation.

This set is designed for heavy to severe duty performance applications, making them a solid choice for serious racers and builders looking to push their engines. While these pistons are built for high performance, please note they are not CARB approved and cannot be shipped to California. Ensure you consult manufacturer specifications for compatibility with your specific engine build and cylinder head combination.
