What is the compression ratio with these pistons?

These Mahle MS pistons contribute to a 9.6:1 compression ratio when installed in the Ford EcoBoost 2.3L engine. This is achieved through the piston's -6.5cc dish volume combined with the engine's specific cylinder head and stroke.

What material are these pistons made from?

The pistons are made from 4032 aluminum. This material is chosen for its strength, good heat tolerance, and resistance to expansion, making it suitable for performance engine applications.

Are these pistons compatible with all Ford EcoBoost 2.3L engines?

These pistons are specifically designed for the Ford EcoBoost 2.3L engine. However, due to variations in engine builds, it is always best to confirm compatibility with your specific vehicle's engine code and consult with your engine builder or refer to Mahle's technical documentation.
