Wiseco AC/HON B 4v DOME +8.25 STRUT 8150XX Piston Shelf Stock Kit

If you're rebuilding the engine in your 1990-2001 Acura Integra, 1994-1997 Honda Civic del Sol, or 1999-2000 Honda Civic, these Wiseco Professional Series pistons are built for serious performance. They are forged from 2618 aluminum right here in the USA, which gives them improved tensile strength over cast pistons, making them well-suited for heavy or severe duty race applications. This set is designed for the B16 engine, with a bore size of 81.50 mm and a dome shape that works with an 8.25:1 compression ratio.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and features to improve ring seal, all contributing to better performance and durability. The crown is fully machined, and they include forced pin oiling to keep the wrist pins lubricated under high stress. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These are not your average pistons; they're made for builders who are pushing the limits of their engines.

This kit includes a set of four pistons, along 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.
