Wiseco BMW S14B23 94.50 mm Bore 30.22 mm CH -38.00 CC Piston Set

If you're rebuilding the engine for your 1988-1991 BMW M3, especially for serious racing or heavy-duty use, this Wiseco forged piston set is built to handle the demands. These pistons are designed for the S14B23 engine, featuring a 94.50 mm bore and a specific compression height to match the European S14 application.

Wiseco crafts these pistons from 2618 aluminum, chosen for its improved tensile strength, making them well-suited for high-performance conditions. They come with precision ring grooves, anti-detonation grooves, and features designed to improve ring seal, all contributing to better engine performance and durability under severe duty. The piston crown is fully machined, and they include forced pin oiling for better lubrication. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

This set includes four pistons, ready for your performance build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
