Wiseco Mercedes M102E25 95.50 mm Bore 38.90 mm CH -10.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious engine builds in your 1986-1987 Mercedes-Benz 190E. The 95.50 mm bore size and -10.00 CC combustion chamber volume are specific to the M102E25 engine, ensuring a precise fit for rebuilding or upgrading your powerplant. This set includes four pistons, each fully machined for consistent performance.

Wiseco's Professional Series pistons are designed for heavy to severe duty applications. They feature precision ring grooves, anti-detonation grooves, and other features to improve ring seal, which is crucial for maintaining compression and preventing blow-by under high stress. The pistons also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine health and longevity. Forced pin oiling is also incorporated to ensure proper lubrication of the wrist pin.

This set is a solid option for builders looking for durable, high-performance pistons. 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.
