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

If you're rebuilding the engine in your 1990-2001 Acura Integra, especially for serious racing or heavy-duty performance, this Wiseco Professional Series piston set is built to handle the stress. These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of severe duty race applications.

Wiseco has packed these pistons with features to ensure performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and the forced pin oiling helps keep the wrist pins lubricated under extreme conditions. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure, a common issue in high-performance engines.

This set includes four pistons, each with an 81.50 mm bore and a dome that adds +5cc to the combustion chamber volume, designed for specific engine builds. They are intended for use with the Honda B18 engine and include premium rings. Please note that these pistons are not CARB approved and cannot be shipped to California.
