Wiseco 02-06 Acura/Honda K20/RSX-S 86.5mm Bore .020 Oversize 11.0:1 CR Dome Dish Piston

This Wiseco piston set includes four forged pistons, ready to be installed in your 2002-2006 Acura RSX Type-S or Honda K20A engine. These pistons are designed to replace your stock components with a performance-oriented upgrade, featuring an 86.5mm bore and a .020 inch oversize dimension, along with an 11.0:1 compression ratio dome dish. They are built from 2618 aluminum, chosen for its strength, and are forged and machined right here in the USA.

Wiseco has packed these pistons with features for demanding applications. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The piston crown is fully machined, and they include forced pin oiling to ensure the wrist pins stay lubricated under high stress. The ArmorGlide skirt coating helps reduce friction, resist seizure, and keep operation quieter, all contributing to better durability in heavy to severe duty race builds.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine rebuild, ensure you have all necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
