Wiseco BMW S14B23 94.00 mm Bore 32.00 mm CH -2.00 CC Piston Set

If you're rebuilding the high-performance S14 engine in your 1988-1991 BMW M3 for serious racing, these Wiseco forged pistons are a solid choice. They're designed to handle the demands of heavy to severe duty applications, giving you the confidence to push your engine's limits. This set includes four pistons, each precisely machined to a 94.00 mm bore size.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, making them well-built for racing environments. They feature precision ring grooves, anti-detonation grooves, and enhanced ring seal features to ensure reliable performance under stress. The piston crowns are fully machined, and they incorporate forced pin oiling to keep critical components lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, contributing to a more durable and quieter operation.

This piston set is specifically built for performance applications and is not CARB approved, meaning it cannot be shipped to California. For a complete rebuild, ensure you have all necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
