Wiseco Acura 4v DOME +5cc STRUTTED 81.0MM Piston Shelf Stock

Wiseco is well-known for making strong, reliable engine components for performance builds. If you're working on a Honda B18 engine, especially for racing or heavy-duty use, these Professional Series pistons are a solid option. They're made from 2618 aluminum, which gives them improved tensile strength, and they're forged and machined right here in the USA.

These pistons feature a dome with a +5cc volume and a strutted design, and they have a bore size of 81.0mm. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, and resists seizing. The crown is fully machined, and they include forced pin oiling to keep things well-lubricated under demanding conditions.

These are built to handle heavy to severe duty applications, making them a great choice for serious racers and builders looking to push their engines. Keep in mind these are not CARB approved and cannot be shipped to California.
