The Ford XUJK is a 1,999 cc, inline‑four turbo‑petrol engine produced between 2020 and 2025. It features a DOHC 16‑valve architecture, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it delivers 177 kW (240 PS) and 370 Nm of torque, with a broad powerband optimized for responsive daily driving and highway overtaking.
Fitted to performance-oriented models such as the Focus ST, Kuga ST‑Line X, and Puma ST, the XUJK was engineered to balance sporty character with modern emissions compliance. Emissions control is achieved through cooled exhaust gas recirculation (EGR), a gasoline particulate filter (GPF), and precise lambda control, meeting Euro 6d standards across all production years.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) cam follower, highlighted in Ford Technical Service Bulletin TSB‑22‑1104. This issue arises under sustained high-load conditions and is linked to marginal lubrication at the cam-follower interface. From early 2023, Ford implemented a revised HPFP design with hardened contact surfaces and improved oil feed geometry.
All production years (2020–2025) comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/8921).
The Ford XUJK is a 1,999 cc inline‑four turbo‑petrol engineered for compact performance models (2020–2025). It combines direct injection with a twin‑scroll turbocharger to deliver strong mid-range torque and agile throttle response. Designed to meet Euro 6d standards, it balances sporty character with regulatory compliance.

The twin-scroll turbo delivers immediate throttle response ideal for spirited driving but demands strict adherence to oil change intervals (max 16,000 km or 12 months) using only Ford WSS-M2C949-A (0W-20) oil to protect the HPFP and timing chain. Sustained high-load use—such as track days or mountain driving—without adequate cooldown can accelerate HPFP cam follower wear. The GPF requires regular highway driving (>20 minutes at >60 km/h) to enable passive regeneration; frequent short urban trips may trigger regeneration warnings. Revised HPFP units from early 2023 (per TSB 22-1104) offer improved durability.
Oil Specs: Requires Ford WSS-M2C949-A (0W-20) specification (Ford Owner Handbook 2021). Not interchangeable with ACEA C2/C3 oils.
Emissions: Euro 6d compliance applies to all 2020–2025 models (VCA Type Approval #VCA/EMS/8921).
Power Ratings: Measured under ISO 1585 standards. Peak output requires RON 95+ fuel (Ford TIS Doc. T23088).

The Ford XUJK was used across Ford's C‑Car and CD‑Car platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—enhanced cooling in the Focus ST, reinforced mounts in the Kuga ST‑Line X, and revised ECU calibration in the Puma ST—and from early 2023 the HPFP upgrade created minor service part interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Ford TIS T23088). The 8th VIN digit indicates engine family ('J' for 2.0L EcoBoost). All XUJK units feature a black plastic cam cover with '2.0 ECoboost' branding. Critical differentiation from earlier 2.0L EcoBoost: XUJK uses direct injection, GPF, and revised turbo housing. ECU part numbers beginning with 'HC4T‑12A650‑*' denote XUJK applications. Pre-2023 and post-2023 HPFPs are not interchangeable due to cam follower redesign (Ford TSB 22‑1104).
The XUJK's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear in early builds, with elevated incidence in sustained high-load or hot-climate use. Ford internal quality data from 2023 indicated a measurable uptick in HPFP replacements before 70,000 km in pre-2023 units, while UK DVSA records show low emissions-related MOT failures due to robust GPF regeneration logic. Aggressive driving without cooldown periods increases thermal stress, making correct oil spec and interval adherence critical.
