mountune MRX Cylinder Head w Camshafts - 1.6L EcoBoost
The mountune MRX Cylinder head upgrade for the 1.6L EcoBoost (Fiesta ST) features dyno and flow bench-tested improvements that produce maximum reliable power across a wide RPM range.
Each cylinder head is based on a new genuine Ford ST casting that is inspected before receiving a precision NEWEN valve seat profile.
The throat of each port is opened up to remove obstructions and then blended into the valve seat to improve flow.
Intake airflow is improved by 51% and exhaust airflow is improved by 24% compared to an otherwise stock 1.6L EcoBoost Cylinder head.
