The mountune MRX Cylinder head upgrade for the 2.3L EcoBoost (Focus RS / Mustang EcoBoost) 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 RS 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 44% and exhaust air flow is improved by 28% compared to an otherwise stock 2.3L Cylinder head.
