Wiseco AC/HON B 4v DOME +8.25 STRUT 8425XX Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your Honda B16A engine. The material choice here means improved tensile strength, which is crucial when you're pushing your engine hard, especially in heavy-duty or severe race applications. This set is designed to handle the demands of high-performance builds where reliability is just as important as power.

Wiseco has packed these pistons with features to ensure they perform and last. You'll find precision machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal, helping to keep combustion where it belongs. The crown is also fully machined, and they include forced pin oiling to keep the wrist pins lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life.

This kit includes four pistons, each with an 84.25 mm bore and a dome profile. Remember, 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.
