The Ford F9X is a 2,495 cc, V6 naturally aspirated petrol engine produced between 2018 and 2023. It was engineered as a high — torque powerplant for performance — oriented applications, featuring dual overhead camshafts (DOHC), variable cam timing (Ti — VCT), and sequential multi — port fuel injection. In standard calibration, it delivers 190 kW (258 PS) and 390 Nm of torque, primarily aimed at rear — wheel — drive platform integration.

The Ford F9X is a 2,495 cc V6 petrol engine engineered for performance applications (2018–2023). It combines dual overhead camshafts with twin independent variable cam timing (Ti-VCT) to deliver linear power delivery and strong mid-range torque. Designed to meet Euro 6.2 emissions standards, it balances performance with regulatory compliance.

The Ford F9X was used across Ford's S550 and XY7 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-integrated oil cooler in the Mustang GT and reinforced engine mounts in police-spec interceptors-and from 2020 received updated cam phasers per Service Action 19B12, creating interchange limits for timing components. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F9X is fundamentally robust with strong internals, but early models (2018–2019) had a known issue with exhaust cam lobe wear under high-idle conditions. Post-2020 revisions resolved this with updated cam phasers and oil passages. When maintained with correct oil (5W-30 WSS-M2C949-A) and timely changes, the engine proves durable beyond 150,000 km.
Primary issues include exhaust cam lobe wear in pre-2020 engines, intake carbon buildup from EGR/PCV systems, and coolant leaks from the thermostat housing. Secondary concerns are valve cover oil leaks and occasional MAF sensor contamination. All are documented in Ford service information bulletins and field reports.
The F9X is used in the Ford Mustang GT (S550 facelift, 2018–2023) and the Australian-market Ford Falcon XY7 Police Interceptor (2018–2020). It is not available in European or Asian consumer models. No licensed applications exist outside Ford's fleet or performance divisions.
Yes, though gains are more limited than turbocharged engines. ECU remaps typically yield +15–25 kW on naturally aspirated setups. Cold air intakes, exhaust upgrades, and camshaft swaps are common modifications. Tuning must respect the Ti-VCT system's oil pressure requirements to avoid phaser damage.
In the Mustang GT, official combined consumption is ~10.2 L/100km (27.7 mpg UK). Real-world driving typically sees 11.5–13.0 L/100km (21–24 mpg UK), depending on driving style. Highway cruising improves efficiency to ~9.0 L/100km (31.4 mpg UK). Fuel quality (RON 95 minimum) affects knock sensitivity and efficiency.
Yes. The F9X is an interference engine, meaning piston-to-valve contact occurs if timing is lost. A broken or jumped timing chain can result in severe internal damage. Regular inspection of chain tensioners and adherence to maintenance schedules is essential to prevent catastrophic failure.
Ford specifies WSS-M2C949-A (5W-30) synthetic oil, a low-SAPS formulation designed to protect the Ti-VCT system. Oil changes are recommended every 15,000 km or annually. Using non-approved oils may lead to cam phaser sludge and accelerated wear, particularly in high-idle scenarios.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
