The Ford NEN is a 1,299 cc, inline‑four naturally aspirated petrol engine produced between 2000 and 2004. It features a single overhead camshaft (SOHC), 8‑valve architecture and sequential multi‑point fuel injection. In standard form it delivered 55 kW (75 PS) at 5,250 rpm and 110 Nm of torque at 3,250 rpm, offering responsive urban drivability with modest fuel consumption.

All production years 2000–2004 meet Euro 3 standards .
The Ford NEN is a 1,299 cc inline‑four SOHC petrol engine engineered for compact city cars (2000–2004). It combines sequential multi‑point fuel injection with a three‑way catalytic converter to deliver light‑weight efficiency and straightforward maintenance. Designed to meet Euro 3 emissions, it balances urban agility with low running costs.

The Ford NEN was used across Ford's Mk4 Fiesta and Ka (facelift) platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Ka for NVH reduction and modified airbox routing in the Fiesta—and from mid‑2001 the camshaft metallurgy update, creating minor 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The NEN offers simple, cost-effective motoring but early units (2000–mid-2001) suffer from camshaft wear. Post-mid-2001 engines with updated cams are significantly more durable. Regular oil changes with Ford-approved 5W-30 and avoiding excessive idling greatly improve longevity.
Top issues include exhaust cam lobe wear (early engines), throttle body fouling, ignition coil failure, and coolant flange leaks. Cam wear is documented in Ford SIB 01S09; other faults are routine for early-2000s small petrol engines.
The NEN powered the Ford Fiesta Mk4 (2000–2002, 1.3i variants) and the facelifted Ka (2000–2004, 1.3i). No other Ford or partner-brand vehicles used this engine. All are Euro 3-compliant with transverse front-engine layout.
Limited tuning potential. The SOHC 8-valve design restricts airflow; mild gains (~5–8 kW) are possible via remap and induction/exhaust upgrades. However, the bottom end isn’t designed for high stress, and cam wear risk increases with aggressive tuning.
Real-world consumption is ~6.8 L/100km (city) and ~4.9 L/100km (highway), or about 41 mpg UK combined. In mixed driving, expect 38–44 mpg (UK). Economy suffers if cam wear or ignition issues are present.
No. The NEN is a non-interference (free-running) engine. If the timing chain fails, pistons will not contact valves, preventing catastrophic damage—though the engine will stop running.
Ford specifies SAE 5W-30 oil meeting WSS‑M2C913‑A (or ACEA A3/B3). Change every 15,000 km or annually. Correct oil is essential to protect the camshaft, especially in early-production engines.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
