Wiseco AC/HON B 4v DOME +8.25 STRUT 8125XX Piston Shelf Stock Kit

Machined from 2618 aluminum, these Wiseco pistons are built for serious performance in your Honda B16A engine. The +8.25cc dome volume is a specific design choice that changes the compression ratio, so it's important to know what your target compression is before installing. This set is designed for 4-valve cylinder heads and features an 81.25 mm bore size.

Wiseco builds these Professional Series pistons for heavy to severe duty race applications. They include precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The crown is fully machined, and they feature forced pin oiling for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, making for quieter operation and improved durability under demanding conditions.

This kit includes a set of four pistons. Remember 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 details.
