Mahle MS Piston Set Ford 2.3L EcoBoost 87.5mm Bore 83mm Stroke 156mm Rod -7cc 9.3 CR Set of 4

This Mahle MS Piston Set includes four forged pistons, specifically designed for the Ford 2.3L EcoBoost engine. Each piston features an 87.5mm bore and a 9.3:1 compression ratio, making them a solid choice for rebuilding or upgrading your engine's top end. The set comes with pistons, and you'll need to source rings, connecting rods, and bearings separately to complete the assembly.

Mahle is known for its well-built engine components, and these pistons are no exception. They are constructed from 2618 aluminum, a material chosen for its strength and ability to handle the stresses of performance applications. The pistons have a compression height of 32.8mm and a dish volume of -6.5cc, which contributes to the overall 9.3:1 compression ratio. The included rod length is 149.3mm with a 22.5mm pin diameter, ensuring proper fitment within the engine's rotating assembly. Each piston weighs approximately 376 grams, contributing to a balanced rotating assembly when installed correctly.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and procedures. Because these are performance-oriented components, proper balancing of the rotating assembly is crucial for engine longevity and smooth operation. Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the Mahle installation instructions for detailed guidance.
