Wiseco BMW S14B23 94.00 mm Bore 30.22 mm CH -38.00 CC Piston Set

This piston set from Wiseco includes four forged pistons, designed specifically for the 1988-1991 BMW M3's S14B23 engine. These aren't your average pistons; they're built for serious performance applications where durability and strength are paramount. Wiseco uses 2618 aluminum, a well-known material for its improved tensile strength, making these pistons a solid choice for demanding engine builds.

You'll find precision in every detail, from the machined crown to the carefully crafted ring grooves. These grooves are designed for improved ring seal, and the pistons also feature anti-detonation grooves to help prevent damage under high stress. The ArmorGlide skirt coating is applied to reduce friction and resist seizure, contributing to quieter operation and longer life, especially in severe duty scenarios. Wiseco also incorporates forced pin oiling to ensure the wrist pins stay well-lubricated.

This set is intended for builders who are pushing their engines hard, whether for track use or other severe duty applications. Remember 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.
