High-Performance Forged Piston Kit for Ford Mk8 Fiesta ST & Puma ST

Description

The mountune forged piston upgrade offers owners of both Mk8 Fiesta ST and Puma ST a credible option for safely increasing their engine’s ability to run high-power and high-torque outputs and their associated cylinder pressure increases, as well as to safely increase maximum engine revs.
These 84mm (standard bore) pistons work in harmony with the mountune steel rod upgrade, or any other uprated rod of the same length that uses a 21mm gudgeon pin and maintains the OE 10:1 compression ratio.
