The mountune MRX Cylinder head upgrade for the 2.0L EcoBoost (Focus 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 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.
The exhaust port is blended to match the factory turbo port size to enhance flow.
Intake airflow is improved by 44% and exhaust air flow is improved by 19% compared to an otherwise stock 2.0L Cylinder head.
