Wiseco Acura 4v Domed +8cc STRUTTED 89.0MM Piston Shelf Stock *SINGLE PISTON ONLY*

This is a single Wiseco 89mm domed piston, specifically designed for Honda K20A engines. It's built for serious racers and builders who need a piston that can handle heavy to severe duty performance applications. The domed shape and +8cc volume are part of its design for specific engine builds, and it features a strutted construction for added durability.

Wiseco forges and machines these pistons in the USA from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The piston crown is fully machined, and it includes forced pin oiling to keep things lubricated. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

Keep in mind this piston is sold individually, so you'll need to order the correct quantity for your engine. It's also important to note that this part is not CARB approved and cannot be shipped to California.
