Wiseco Acura 4v DOME +5cc STRUTTED 81.25mm Piston Shelf Stock Kit

Forged from 2618 aluminum in the USA, these Wiseco pistons are built for serious performance in your Honda B18 engine. The 81.25mm bore size and +5cc dome volume are specific choices for builders looking to increase compression and power for heavy to severe duty race applications. This kit includes four pistons, each fully machined with features like precision ring grooves, anti-detonation grooves, and forced pin oiling to ensure reliable operation under extreme conditions.

The pistons also feature an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when pushing an engine hard. The strutted dome design adds further strength to the piston crown, making these a solid option for builders who need components that can handle significant stress and heat.

This set is designed for sport compact builds and comes with premium rings. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
