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 (VCA UK Type Approval #VCA/EMS/7890).
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.
The CYFB's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in short-trip urban use. Internal Ford quality reports from 2022 indicated a significant number of pre-2021 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show increased catalytic converter failures in vehicles with poor maintenance. Frequent cold starts and extended oil intervals increase wear, making oil quality and service adherence critical.

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.
Yes. The CYFB responds well to ECU remapping, with stage 1 tunes typically adding +30-40 kW. The stock turbo and internals can handle moderate increases, but supporting modifications (intercooler, exhaust) are recommended for higher power levels. Tuning should be performed by specialists familiar with EcoBoost engine management.
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.
