Product Details

If you're building a high-performance Honda B16A engine for serious competition, you need pistons that can handle extreme stress. This Wiseco Professional Series forged piston kit is designed specifically for those demanding applications. These aren't your average replacement pistons; they're built from the ground up for racing, offering improved tensile strength and durability under heavy loads.

Crafted from 2618 aluminum in the USA, these pistons are forged and machined to exacting standards. You'll find precision ring grooves, anti-detonation grooves, and features that enhance ring seal, all contributing to better performance and longevity. The crown is fully machined for accuracy, and they even include forced pin oiling to keep critical components lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is crucial when you're pushing your engine to its limits.

This set includes four pistons, each with an 81.00 mm bore and a 29.85 mm compression height, using a 0.827-inch pin diameter. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for severe duty performance builds where reliability and strength are paramount.
