The Ford CYFC is a 1,999 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It belongs to the second generation of Ford's EcoBoost engine family, featuring direct fuel injection, twin-independent variable cam timing (Ti-VCT), and an intercooled turbocharger. In standard tune it delivers 147 kW (200 PS) and 320 Nm of torque, offering a balance of responsive performance and improved efficiency for mid-size applications.
Fitted to models such as the Focus ST-Line, Kuga, and Edge, the CYFC was engineered for drivers seeking strong mid-range power delivery and everyday drivability. Emissions compliance was achieved through a three-way catalytic converter and cooled exhaust gas recirculation (EGR), allowing it to meet Euro 6d-Full standards across its production run. The engine features a compact low-inertia turbocharger for reduced lag and enhanced throttle response.
One documented concern is carbon buildup on intake valves due to port versus direct injection design limitations, highlighted in Ford Service Information Bulletin 19 05 03. This issue is exacerbated by short-trip driving and infrequent oil changes. Later production revisions included updated oil spray jets and revised ECU logic to mitigate deposit formation.

Production years 2018–2023 meet Euro 6d-Full standards (VCA UK Type Approval #VCA/EMS/6789).
The Ford CYFC is a 1,999 cc inline-four turbocharged petrol engineered for mid-size passenger vehicles (2018-2023). It combines direct fuel injection with twin-independent variable cam timing (Ti-VCT) and an intercooled turbocharger to deliver responsive throttle characteristics and strong mid-range torque. Designed to meet Euro 6d-Full standards, it balances performance with emissions compliance and fuel efficiency.

The turbocharged inline-four provides strong mid-range torque ideal for daily driving but requires adherence to 15,000 km oil change intervals using Ford WSS-M2C946-C (5W-30) to prevent turbocharger oil coking and timing chain wear. The HDEV6 high-pressure fuel pump demands premium unleaded fuel (RON 95 minimum) to prevent injector deposits and knock. Intake valve carbon buildup is common in short-trip driving; Ford SIB 19 05 03 recommends periodic walnut blasting and ECU updates. Avoid prolonged idling after high-load operation to allow turbo cooldown. The double-row timing chain is more robust than prior designs but remains sensitive to oil degradation.
Oil Specs: Requires Ford WSS-M2C946-C (5W-30) specification (Ford SIB 19 05 03). Meets Ford WSS-M2C946-B and ACEA C2/C3.
Emissions: Euro 6d-Full certification applies to all production years (2018–2023) (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349 standards. 147 kW output requires RON 95+ fuel (Ford TIS Doc. C21015).

The Ford CYFC was used across Ford's C2/CD6 platforms with transverse mounting. This engine received platform-specific adaptations-revised torque mounts in the Kuga and enhanced cooling in the Edge-and from 2020 the facelifted Focus Mk4 models adopted updated ECU calibrations, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side engine block near the exhaust manifold (Ford TIS C20450). The 8th VIN digit indicates engine family ('G' for EcoBoost). Pre-2020 models have silver valve covers with black plastic intake manifolds; post-2020 units use black valve covers. Critical differentiation from non-turbo variants: CYFC features intercooler piping and turbocharger housing on the right side. Service parts require production date verification - ECU calibrations for engines before 03/2020 are incompatible with later units due to revision per Ford SIB 19 05 03.
The CYFC's primary reliability risk is intake valve carbon buildup, with elevated incidence in urban-driven examples. Internal Ford quality reports from 2021 noted a significant number of pre-2020 units requiring intake cleaning before 120,000 km, while UK DVSA records show increased catalytic converter failures in high-mileage applications. Short-trip driving and use of non-premium fuel increase deposit formation, making fuel specification and driving pattern adherence critical.
