Wiseco Ford Focus ST225/Mondeo ST220 2.5L 20V 84mm Bore 9:1 CR +0.1 Dome Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle heavy to severe duty. They are designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

Each piston features precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they come with forced pin oiling to keep things well-lubricated. Plus, they have an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes operation quieter. This set is for Ford 2.5L 20V engines with an 84mm bore and a 9:1 compression ratio, with a +0.1 dome to help achieve that ratio.

This set includes five pistons, the compression height is 30.50mm, and the pin diameter is 0.9055 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds and are a solid option when you're pushing your engine hard.
