The Ford KLBA is a 2,998 cc, V6, twin — turbocharged petrol engine produced between 2021 and 2023. It forms part of Ford's EcoBoost family, featuring direct fuel injection, twin — independent camshaft timing (Ti — VCT), and dual high — flow turbochargers to deliver high — performance output. In standard tune, it produces 294 kW (400 PS) and 563 Nm of torque, paired exclusively with a 10 — speed automatic transmission.

All production years 2021–2023 meet Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/9012).
The Ford KLBA is a 2,998 cc V6 twin-turbocharged petrol engine engineered for high-performance applications (2021–2023). It combines direct fuel injection with Ti-VCT and dual turbocharging to deliver strong acceleration and sustained power output. Designed to meet Euro 6d-TEMP standards, it balances track-capable performance with modern emissions control.

The Ford KLBA was used across Ford's CD6 platform with longitudinal mounting and shared architecture with Lincoln for select North American applications. This engine received platform-specific adaptations-reinforced oil pans in the F-150 Raptor and revised cooling paths in the Mustang Mach 1-and from 2022 the facelifted Mustang adopted the KLBA-TU variant with enhanced fuel pump durability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The KLBA's primary reliability risk is high-pressure fuel pump (HPFP) wear, with elevated incidence in performance and towing use. Ford's internal quality report from 2022 indicated a significant share of pre-2022 engines required HPFP service before 120,000 km, while UK DVSA records show increased catalytic converter failures linked to lean-running conditions under load. High-load cycles and infrequent cooldowns increase thermal stress, making fuel quality and operational discipline critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The KLBA engine is generally robust when maintained properly, though pre-2022 models have documented HPFP wear issues. Later revisions (post-2022) show improved durability with updated hardware. Regular oil changes using Ford WSS-M2C946-C1 (5W-30) and use of high-octane fuel help prevent carbon buildup and ensure longevity. Well-maintained units reliably exceed 150,000 km.
The most frequent issues are high-pressure fuel pump wear, intake carbon buildup, and coolant leaks from the thermostat housing. Less common are cold-start timing chain rattle and MAF sensor contamination. These are documented in Ford service bulletins and addressed through updated parts and maintenance procedures.
The KLBA engine is used in the Ford Mustang Mach 1 (2021–2023), F-150 Raptor (2022–2023), and Lincoln Aviator (2023) in 3.0L EcoBoost form. All applications are rear-wheel or all-wheel drive with longitudinal engine layout and meet Euro 6d-TEMP standards. The engine functions as the high-performance combustion component in Ford’s performance and off-road lineup.
Yes. The KLBA responds well to ECU remapping, with stage 1 tunes typically adding +50–70 kW safely. Stock internals handle increased torque, but supporting modifications (intercooler, exhaust) are recommended for higher stages. Tuning must preserve EGR and emissions functions to remain road-legal and avoid DPF-related faults.
In combined driving, the KLBA achieves approximately 12.5–14.0 L/100 km (20–23 mpg UK). Highway efficiency improves to ~11.0 L/100 km (~26 mpg UK), while city driving may reach 16.0 L/100 km (~18 mpg UK). Real-world consumption depends on driving style, with aggressive or off-road use reducing efficiency significantly.
No. The KLBA uses a non-interference valvetrain design. If the timing chain fails or skips, piston-to-valve contact does not occur, preventing catastrophic engine damage. However, drive loss will disable the engine, so chain and tensioner maintenance remains important for operational reliability.
Ford specifies 5W-30 synthetic oil meeting WSS-M2C946-C1 standard. This low-SAPS formulation protects turbo bearings, GDI injectors, and variable cam timing systems. Oil changes should occur every 15,000 km or annually, using only OEM-approved brands to ensure compatibility and longevity.
