Wiseco Honda R18A 81.00 mm Bore 28.50 mm CH -10.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for demanding applications. This Professional Series piston set is a prime example, built for Honda R18A engines. If you're rebuilding your engine for serious performance or heavy-duty use, these pistons are designed to handle the stress.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength compared to other materials. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is also fully machined. For added durability and smoother operation, they come with an ArmorGlide skirt coating that reduces friction and noise, and helps prevent seizure. The design also includes forced pin oiling to keep the wrist pins well-lubricated under high loads.

This set includes four pistons, each with an 81.00 mm bore and a 28.50 mm compression height. They are intended for sport compact applications and are built to withstand heavy to severe duty performance builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
