About this part

Product Details

Mahle's MS piston set is built for the demanding S85 B50 5.0L V10 engine found in performance BMWs. If you're rebuilding the heart of your V10, these forged pistons are a solid choice for durability and performance. They feature a dome design that contributes to the engine's compression ratio, specifically targeting a 10.1:1 compression with the specified components.

These pistons are forged from 4032 aluminum alloy, a material known for its strength and resistance to thermal expansion, making it well-suited for high-performance applications where temperatures can get intense. Each piston measures 92.00mm in bore diameter with a 27.3mm compression height, designed to work with a 75.2mm stroke and a 140.7mm connecting rod. The pin diameter is 21mm, and each piston weighs in at 366 grams. The dome volume is 2.1cc, which is a key factor in achieving that 10.1:1 compression ratio when paired with the correct cylinder head and gasket combination.

This set includes ten pistons, enough for a complete engine rebuild. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and specifications to ensure proper fitment and performance when rebuilding your S85 engine.
