Wiseco Mazda BP 3.346in Bore 1.201in CH -4.20 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set for Mazda BP engines is a prime example of their commitment to serious racers and builders. These aren't just replacement parts; they're designed from the ground up to handle the demands of heavy to severe duty race builds, giving you the confidence to push your engine's limits.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-performance engines. You'll find precision ring grooves, anti-detonation grooves, and other features specifically added to improve ring seal and overall performance. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their durability and reliability under extreme conditions.

This set includes four pistons, each with a 3.346-inch bore, a 1.201-inch compression height, and a 0.787-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Mazda BP engine for racing, these pistons are a solid option to consider.
