Wiseco BMW S14B23 94.50 mm Bore 32.00 mm CH -32.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength for the demanding S14B23 engine found in the 1988-1991 BMW M3. The pistons feature a 94.50 mm bore and a 32.00 mm compression height, with a -32.00 CC volume in the crown. This set is designed for builders who are serious about performance and durability, intended for heavy to severe duty race applications where reliability is critical.

Wiseco has included several features to enhance performance and longevity. The precision ring grooves are designed for improved sealing, complemented by anti-detonation grooves and additional features that promote better ring seal. The piston crowns are fully machined for accuracy, and they benefit from forced pin oiling to ensure the wrist pin stays well-lubricated under high stress. Additionally, an ArmorGlide skirt coating is applied to reduce friction, minimize noise, and resist seizure, all contributing to a more robust and efficient engine build.

This set includes four pistons, the wrist pins, and premium rings, ready for installation in your S14B23 engine. 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.
