Wiseco Acura 4v Domed +8cc STRUTTED 87.0MM Piston Kit

This kit gets you four Wiseco forged pistons, complete with premium rings and pins, ready to go into your Honda K20A engine. These aren't your average pistons; they're built for serious performance and durability, designed to handle the demands of heavy to severe duty race builds. The 87.00 mm bore size and the +8cc domed volume are key specs for tuning your engine's compression and combustion chamber shape.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, chosen for its improved tensile strength under high stress. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for both power and longevity. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, while also making operation quieter. The fully machined crown and forced pin oiling are further touches that show these are built for tough applications.

Because these are designed for competition, they are not CARB approved and cannot be shipped to California. If you're building a high-performance K20A engine for racing, this set is a solid option to consider for the core of your build.
