What is the compression ratio of these pistons?

These Wiseco pistons feature a 9:1 compression ratio. This is a specific ratio designed for the M102E23 European engine configuration.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide coating on the piston skirts helps to reduce friction between the piston and cylinder wall. It also contributes to seizure resistance and quieter operation of the engine.

Are these pistons compatible with all 1986-1987 Mercedes-Benz 190E models?

This piston set is specifically designed for the M102E23 European engine variant found in the 1986-1987 Mercedes-Benz 190E. It is not CARB approved and cannot be shipped to California.

Product Details

If you're rebuilding the engine in your 1986 or 1987 Mercedes-Benz 190E for serious performance, a set of Wiseco Professional Series pistons is a solid choice. These pistons are built from 2618 aluminum, which offers improved tensile strength, making them well-suited for heavy or severe duty race applications where durability is key. The 96.5mm bore and 9:1 compression ratio are specific to the M102E23 European engine configuration.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and improved ring sealing to ensure optimal performance and longevity. They also include forced pin oiling to keep the wrist pins lubricated under high stress. The crown of each piston is fully machined, and the skirts are treated with an ArmorGlide coating. This coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-performance engines.

This set includes four pistons, rings, and is designed to fit your 190E directly. 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 assembly and break-in procedures.
