Wiseco Honda R18 81.5mm 9.0:1 CR Bore -10cc Dome Piston Shelf Stock Kit

This is a Wiseco forged piston set designed for Honda R18 engines. These pistons are built with a specific bore size of 81.50 mm and a compression ratio of 9.0:1, featuring a -10cc dome. They are intended for sport compact applications and come as a set of four.

Wiseco crafts these Professional Series pistons from 2618 aluminum, a well-built material chosen for its improved tensile strength, making them suitable for heavy to severe duty performance builds. The pistons feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are additional details that contribute to their durability and performance in demanding applications.

This kit is designed for serious racers and builders who need pistons packed with custom-level performance and durability features. Please note that 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.
