What material are these Mahle pistons made from?

These Mahle MS pistons are constructed from 2618 aluminum. This material is chosen for its strength and ability to perform well under high temperatures and pressures commonly found in performance engine builds.

What is the compression ratio of these pistons?

The pistons are designed for a 9.0 compression ratio. The specific volume of the piston dish is -4.5cc, which results in a calculated compression ratio of 9.4:1 when used with compatible engine components.

Are these pistons compatible with all Mitsubishi 4B11T engines?

These pistons are specifically designed for the Mitsubishi 4B11T 2.0L engine. It is important to verify that your engine's specifications, including bore, stroke, and rod length, match the requirements of these pistons before installation.
