Wiseco AC/HON B 4v DOME +8.25 STRUT 8150XX Piston Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston kit is a prime example, built for serious racers and builders who need parts that can handle severe duty. If you're rebuilding the top end of your Honda B16A engine for demanding use, these pistons are designed to meet that challenge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is also fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

This set includes four pistons, each with an 81.50 mm bore and a +8.25cc dome volume, suitable for a +8.25 compression ratio. They have a 30.00 mm compression height and use a 0.827-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
