What is included in this Mahle piston set?

This Mahle MS Piston Set includes six pistons. Each piston is designed with a 100mm bore, 82.8mm stroke, 141.99mm rod length, and a 22mm pin. The dish volume is -13.2cc, resulting in a 12.0:1 compression ratio.

What is the compression ratio achieved with these pistons?

These pistons are designed to achieve a 12.0:1 compression ratio. This is due to the specific dish volume of -13.2cc combined with the cylinder head and gasket used in your engine build.

Are these pistons compatible with all 3.8L engines?

While designed for 3.8L engines, specific fitment should always be verified with the manufacturer's data. Key dimensions like bore size, stroke, rod length, and pin diameter must match your engine's requirements for proper installation and performance.
