Product Details

Mahle is well-known for making solid engine components, and this MS piston set for the Ford EcoBoost 2.0L is a great example of their work. If you're rebuilding the top end of your Focus or another vehicle with the 2.0L EcoBoost engine, these pistons are built to handle the demands of a performance build.

This set features pistons with an 87.5mm bore and an 83.1mm stroke, designed to work with a 155.87mm rod and a 22.5mm pin. The -7.0cc dish volume contributes to a 9.3:1 compression ratio, which is a common target for modified EcoBoost engines looking for improved power without sacrificing too much drivability. They are constructed from 2618 aluminum, a strong material often used in performance pistons for its durability under high temperatures and pressures. Each piston weighs in at 376g, keeping rotating assembly weight manageable.

This set includes four pistons, ready for installation. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
