The Ford SFB is a 1,596 cc, inline‑four turbo‑petrol engine produced between 2010 and 2015. It features gasoline direct injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivered 118 kW (160 PS) and 240 Nm of torque, offering responsive urban performance with compact packaging.
Fitted to models such as the Focus (MK3), C — Max, and Grand C — Max, the SFB was engineered for efficiency — focused drivers seeking punchy low —…
All production years (2010–2015) meet Euro 5 standards .
The Ford SFB is a 1,596 cc inline‑four turbo‑petrol engineered for compact hatchbacks and MPVs (2010–2015). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver brisk low‑rpm response and spirited acceleration. Designed to meet Euro 5 emissions standards, it balances sporty character with regulatory compliance.

The Ford SFB was used across Ford's C1/C346 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised cooling ducting in the Focus and reinforced mounts in the C-Max—and from 2015 the facelifted Focus adopted the updated 1.5L EcoBoost, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The SFB offers strong performance but early units (2010–2012) had camshaft HPFP lobe wear concerns. Post-TSB engines (2013+) are significantly more robust. With proper maintenance—95+ RON fuel, correct oil, and cooldown after hard use—it can deliver reliable service beyond 200,000 km.
Top issues include camshaft HPFP lobe wear (pre-2013), turbo oil coking from hot shutdowns, intake valve carbon buildup (due to direct injection), and plastic thermostat housing leaks. All are documented in Ford TSBs and service manuals.
The SFB powered the 2010–2014 Focus MK3 1.6 EcoBoost 160 PS, 2010–2015 C-Max and Grand C-Max 1.6 EcoBoost variants. It was never used in the Fiesta ST or later Focus RS, which adopted different EcoBoost engines.
Aftermarket ECU tuning is common on the SFB platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Focus, expect ~9.1 L/100km (city), ~5.9 L/100km (highway), or ~37 mpg UK combined. Aggressive driving reduces this significantly. C-Max variants achieve slightly better economy due to lower weight and gearing.
Yes. The SFB is an interference engine. Timing chain failure—though rare due to robust front-mounted design—can cause piston-to-valve contact and catastrophic damage. No timing belt service is required.
Ford specifies SAE 5W-30 oil meeting WSS-M2C946-A standard. This low-SAPS formulation protects the turbo and emissions system. Change every 16,000 km or 12 months, whichever comes first.
