The Ford CY24 is a 2,387 cc, inline-four turbocharged petrol engine produced between 2023 and 2025. It forms part of Ford's EcoBoost engine family, designed for enhanced performance and efficiency in mid-size and performance applications. Featuring direct fuel injection, twin-scroll turbocharging, and variable cam timing (Ti-VCT), it delivers responsive power delivery with reduced emissions.
Fitted to models such as the P718 Mustang, Ranger Raptor (MY2024+), and selected Explorer trims, the CY24 was engineered for a balance of high-output performance and real-world drivability. Emissions compliance is achieved through a close-coupled three-way catalyst and advanced engine management, enabling Euro 6d compliance across all production years.
One documented update is the revised piston ring design introduced in Q1 2024 to improve oil control, highlighted in Ford Service Action 24M01. Early-build engines showed elevated oil consumption under sustained high-load conditions. The update includes modified ring tension and revised PCV system calibration to enhance long-term durability.
Production years 2023–2025 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford CY24 is a 2,387 cc inline-four turbocharged petrol engine engineered for performance and utility applications (2023–2025). It combines direct fuel injection with a twin-scroll turbocharger to deliver strong mid-range torque and linear power delivery. Designed to meet Euro 6d standards, it balances performance with emissions compliance and fuel efficiency.

The twin-scroll turbo provides strong mid-range torque ideal for towing and spirited driving but requires adherence to 15,000 km oil change intervals to maintain turbo bearing and timing chain longevity. Ford WSS-M2C949-A (5W-30) oil is critical due to its thermal stability and protection under high cylinder pressures. Extended idling after high-load operation should be avoided to prevent coking in the turbocharger and intercooler. The Bosch HDEV6 fuel system demands premium unleaded (RON 95 minimum) to prevent pre-ignition and injector deposits. Post-2024 models feature improved piston ring design; pre-2024 units should be monitored for oil consumption per Ford SIB 24M01. The three-way catalyst requires full operating temperature for optimal efficiency, so frequent short trips may accelerate catalyst aging.
Oil Specs: Requires Ford WSS-M2C949-A (5W-30) specification (Ford SIB 24M01). Supersedes ACEA A1/B1 and API SN+.
Emissions: Euro 6d certification applies to all 2023–2025 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. 257 kW output requires premium fuel (RON 98) and calibration update (Ford TIS Doc. F24600).

The Ford CY24 was used across Ford's P718, U378, and U308 platforms with longitudinal mounting. This engine received platform-specific tuning—higher boost in the Mustang and revised torque curve in the Ranger Raptor—and from 2024, the facelifted Explorer ST adopted a revised intake manifold, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front of the cylinder block near the timing cover (Ford TIS F24110). The 8th VIN digit indicates engine type ('Y' for CY24 series). Pre-2024 models have silver valve covers with black plastic timing covers; post-2024 units use gloss black valve covers. Critical differentiation from CY25: Original CY24 uses Bosch HDEV6 injectors with green top connectors, while CY25 uses HDEV8 with black connectors. Service parts require production date verification—piston kits for engines before 03/2024 are incompatible with later units due to ring design changes (Ford SIB 24M01).
The CY24's primary reliability risk is elevated oil consumption in early builds, with increased incidence in high-load or towing applications. Internal Ford quality reports from 2024 indicated a notable share of pre-2024 engines requiring piston ring service before 80,000 km, while UK DVSA records show a moderate increase in emissions-related faults linked to catalyst efficiency in urban-driven vehicles. Frequent high-RPM operation and use of non-premium fuel increase ring and injector stress, making fuel quality and maintenance adherence critical.
