Wiseco AC/HON B 4v DOME +8.25 STRUT 8100XX Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series piston kit is a prime example, designed for serious racers and builders who need top-tier performance and durability. If you're rebuilding the engine in your 1990-2001 Acura Integra, your 1994-1997 Honda Civic del Sol, or your 1999-2000 Honda Civic, these pistons are built to handle heavy to severe duty race conditions.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding use. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown also contributes to their performance. For added longevity and smoother operation, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter running. Plus, forced pin oiling ensures the wrist pins stay well-lubricated under high stress.

This kit includes a set of four pistons, each with an 81.00 mm bore and a dome that adds +8.25cc volume. The compression height is 30.00 mm, and they use a 0.8268-inch diameter pin. Keep in mind 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.
