Product Description

The Wiseco KE227M835 is a Professional Series forged piston set of 5 for the Ford 2.5L V6 Duratec 25 engine at 83.50 mm overbore (OEM: 82.4 mm). This engine powered the Ford Contour SE/SVT and Mercury Mystique (1995-2000) in North America, the Mercury Cougar (1999-2002), and the Ford Mondeo Mk1/Mk2 including the ST24 and ST200 variants in Europe (1993-2000). Forged from 2618 aluminum for superior tensile strength under extreme thermal and mechanical loads, each piston features ArmorGlide skirt coating, a fully machined crown with precision ring grooves, anti-detonation groove, and forced pin oiling for heavy to severe duty race applications.

Set of 5 -- covers one complete bank of the V6. Confirm finished bore before ordering. Jaguar X-Type/S-Type 2.5L and Mondeo Mk3 2.5L use a different 81.6mm bore variant and are not compatible. Engineered, forged, and machined in the USA by Wiseco.
