Detailed Description

The Mahle S224-3430 piston is engineered for engines that require a standard-size replacement piston with OE-style fit and function. Its dome head and three valve reliefs support the listed Ford Escape, Ford Focus, Mazda Tribute, Ford Escort, Mercury Cougar, Ford Contour, and Mercury Mystique applications, while the coated skirt and controlled expansion help maintain clearance and reduce operating noise. Mahle is a major OE piston manufacturer, and this design reflects the same ring-groove and oil-control features used in original equipment applications. This part cross-references ring set 41724 for the same application.

What This Piston Helps Address

• Worn or scuffed piston skirts
• Loss of compression from piston damage
• Excessive oil consumption related to piston wear
• Engine noise caused by improper piston clearance
• Ring sealing issues from worn ring grooves

Installation Notes and Tips

Verify bore size, compression height, pin diameter, and ring specification before installation. This piston is listed as standard size and is sold without rings, so confirm the correct ring set and machine work requirements for your engine build. Match the dome profile and valve relief layout to the original application before assembly.

Quality Assurance

Mahle manufactures OE-quality pistons and supplies original equipment components for a wide range of engines. The S224-3430 is built to support consistent ring control, fitment accuracy, and durable service in the listed Ford, Mazda, and Mercury applications.
