Wiseco AC/HON B 4v DOME +8.25 STRUT 8550XX Piston Kit

This is a set of four forged pistons from Wiseco, designed for Honda B16A engines. You get the pistons themselves, ready to be installed in your build. These pistons feature a dome shape with a volume of +8.25cc, and they have a bore size of 85.50 mm. They are built from 2618 aluminum, which is known for its improved tensile strength, making them suitable for demanding performance applications.

Wiseco machines these pistons in the USA, and they come with precision ring grooves, anti-detonation grooves, and features aimed at improving ring seal. The piston crown is fully machined, and they incorporate forced pin oiling to ensure the wrist pins stay lubricated. Additionally, they feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These are intended for heavy to severe duty race builds where durability and performance are critical.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for sport compact applications and are a solid option if you're rebuilding the top end of your engine for serious performance use.
