Wiseco Honda / Acura K24/K20 Head 87.25/3.435 Bore +5cc 12.5:1 CR Piston Shelf Stock Kit

If you're building a serious performance engine for your Honda or Acura K24 or K20, this Wiseco forged piston set is designed to handle the demands. These pistons are made for applications where durability and performance under heavy stress are critical, like in serious racing builds. They're built to withstand severe duty use, giving you the confidence to push your engine's limits.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, chosen for its improved tensile strength. The machining process is precise, featuring anti-detonation grooves and other features to improve ring seal and prevent issues like detonation. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pin lubricated under extreme conditions.

This kit includes everything needed for a set of four pistons, with a bore size of 87.25mm and a compression ratio of 12.5:1. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, these Wiseco pistons are a well-built option designed for high-performance applications.
