Mahle MS Volkswagen Beetle Type I/II/III 94.00mm x 45mm CH 82.0mm Stroke Pistons - Set of 4

These Mahle MS pistons are forged from 2618 aluminum, a strong material commonly used for high-performance applications where durability under stress is key. Each piston measures 94.00mm in bore diameter and is designed to work with an 82.0mm stroke, featuring a 45mm compression height (CH) and a 22mm pin diameter. This specific design is intended for Volkswagen Beetle Type I, II, and III engines, often found in the VW/Audi A/C Beetle 2.3L models. The 0cc combustion chamber volume indicates a flat-top piston design, which is typical for naturally aspirated or mild performance builds where precise compression ratio control is important.

The choice of 2618 aluminum for these pistons means they offer good strength and thermal expansion properties, crucial for handling the heat and pressure generated in an air-cooled engine. At 380 grams each, they are relatively lightweight for their size, which helps reduce reciprocating mass in the engine. This can lead to improved engine response and less stress on other rotating components like the crankshaft and connecting rods. Mahle is a well-known name in engine components, and this set is built to meet the demands of rebuilding or upgrading these classic VW engines.

When rebuilding your engine with these pistons, ensure you follow the manufacturer's recommended clearances and installation procedures. Because these are a specific forged piston set, they are often part of a larger engine overhaul. It's important to note that this part is not CARB approved and cannot be shipped to California. Always consult your engine builder or service manual for the precise specifications and assembly instructions to ensure optimal performance and longevity of your engine build.
