Wiseco Acura 4v Domed +8cc STRUTTED 86.5MM Piston Kit

If you're building a high-performance K20A engine for serious racing, Wiseco's Professional Series forged pistons are a solid option. These pistons are designed and built in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. The 86.5mm bore size and +8cc dome volume are specific to certain K20A engine builds, so make sure this matches your project's needs.

Wiseco packs a lot of performance and durability features into these pistons. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, while also making operation quieter. The fully machined crown and forced pin oiling are also notable details for builders pushing their engines hard.

This set includes four pistons, and they are designed to withstand heavy to severe duty performance applications. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful build, always refer to the manufacturer's installation instructions for specific details regarding assembly and tuning.
