The Ford CYFB is a 1,999 cc, inline — four turbocharged petrol engine produced between 2018 and 2023. It belongs to the Ford EcoBoost Gen — 3 family, featuring direct fuel injection, twin — scroll turbocharging, and integrated exhaust manifolding. In standard tune it delivers 140 kW (190 PS) with 320 Nm of torque, offering strong mid — range performance ideal for dynamic driving and towing applications.
Fitted to models such as the Focus ST, Kuga ST — Line, and Edge, the CYFB wa…

Production years 2018–2023 meet Euro 6d-Full standards .
The Ford CYFB is a 1,999 cc inline-four turbocharged petrol engine engineered for performance-oriented passenger vehicles (2018–2023). It combines direct injection with a twin-scroll turbocharger and integrated exhaust manifold to deliver responsive acceleration and robust torque. Designed to meet Euro 6d-Full emissions standards, it balances sporty performance with modern efficiency and emissions control.

The Ford CYFB was used across Ford's C2/CD6 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-tuned intake manifolds in the Focus ST and revised cooling routing in the Edge-and from 2021 the facelifted Kuga adopted updated engine management software, creating interchange limits. 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 CYFB offers strong performance and modern efficiency, but early models (2018-2020) had reliability concerns, particularly high-pressure fuel pump wear. Later revisions (post-2021) improved component durability, so well-maintained examples can be robust. Regular servicing with correct oil (5W-30 Ford WSS-M2C947-B1) and adherence to maintenance intervals greatly enhance longevity.
The most common issues are high-pressure fuel pump failure, intake valve coking due to direct injection, turbo wastegate sticking, and timing chain tensioner wear. These are documented in Ford service bulletins and verified through DVSA inspection data. Preventative maintenance significantly reduces risk.
The 2.0L EcoBoost CYFB engine was used in the Ford Focus ST (2018-2023), Kuga (2018-2023), and Edge (2018-2023). It was not used in other brands or licensed externally. All applications met Euro 6d-Full emissions standards.
Aftermarket ECU tuning is common on the CYFB platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Focus ST 2.0 EcoBoost (140 kW), combined consumption is approximately 7.8 L/100km (~36 mpg UK). Highway driving can achieve ~6.2 L/100km (~45 mpg UK), while city use may reach 9.5 L/100km (~30 mpg UK). Real-world figures depend on driving style, but 30-38 mpg (UK) is typical for mixed conditions.
Yes. The CYFB is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal engine damage. This makes proper maintenance and immediate attention to any timing-related noises essential.
Ford specifies a 5W-30 synthetic oil meeting Ford WSS-M2C947-B1 specification. Using the correct oil is critical for turbocharger and high-pressure fuel pump lubrication. Oil changes should be performed every 15,000 km or annually to maintain reliability and prevent premature wear.
