Wiseco Honda K-Series +10.5cc Dome 1.181X86.0mm Piston Shelf Stock Kit

Wiseco is well-known for making strong engine components, and their Professional Series pistons are built for serious racers and builders. This specific piston set is designed for the Honda K-Series engine, commonly found in the 2002-2006 Acura RSX. These aren't your average pistons; they're packed with features for high-performance and durability, intended for heavy to severe duty race builds where reliability is key.

Each piston is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown of each piston is fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. This set is designed to help you push your engine's limits.

This kit includes four pistons, each with an 86.00 mm bore and a +10.5cc dome volume. The compression height is 30.00 mm, and they use a 0.8661 inch (22.00 mm) pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
