This Mahle MS Piston and Cylinder set includes everything you need to rebuild the heart of your Porsche 964's 3.6L naturally aspirated engine. You get the pistons, cylinders, and associated components designed to work together for a complete engine overhaul. This kit is built for enthusiasts looking to extract more performance from their air-cooled flat-six, featuring a 102mm bore and a 12.6:1 compression ratio. This updated compression ratio is designed to work with specific engine builds, so it's important to ensure it matches your camshafts and tuning for optimal results.

Mahle is a well-known name in engine components, and this set reflects their commitment to well-built parts. The pistons are forged for strength, which is crucial for handling the increased cylinder pressures that come with a higher compression ratio. The cylinders are precision-machined to match the pistons, ensuring a proper seal and efficient operation. The set includes pistons with a 76.4mm stroke, 127mm connecting rods, and a 23mm wrist pin, all critical dimensions for correct engine assembly and performance. The 44.5cc combustion chamber volume is a key specification that contributes to the 12.6:1 compression ratio, a notable increase over stock that can lead to improved power output when properly tuned.

When installing this set, remember that it is not CARB approved and cannot be shipped to California. It's also important to note that this kit is designed for specific engine configurations and may require other supporting modifications, such as updated fuel management and ignition timing, to achieve its full potential and ensure engine longevity. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures.
