The Peugeot NFR (TU5JP4B) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 2004 and 2012. It features a dual overhead camshaft (DOHC) 16‑valve design with multipoint fuel injection and variable valve timing (VVT), delivering 80 kW (109 PS) and 142 Nm of torque. Its aluminum alloy construction and VVT system enabled a balance of efficiency and responsive performance for compact applications.
Fitted primarily to the 207 and 307 models, the NFR was engineered for agile, economical urban and highway driving. Emissions compliance for its era was managed through precise electronic control and a three-way catalytic converter, allowing adherence to Euro 4 standards across its production run.
One documented concern is premature failure of the plastic intake manifold, noted in Peugeot Technical Note 05C. This can lead to vacuum leaks, causing rough idling and increased fuel consumption. The issue stems from material fatigue and heat cycling in the manifold's runner flanges.
Production years 2004–2012 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/7890).
The Peugeot NFR (TU5JP4B) is a 1,587 cc inline‑four naturally aspirated petrol engineered for compact hatchbacks (2004-2012). It combines DOHC 16-valve architecture with variable valve timing to deliver responsive, efficient performance. Designed to meet Euro 4 standards, it balances everyday agility with low running costs.

The DOHC VVT design provides a linear power delivery ideal for spirited driving but requires vigilant monitoring of the plastic intake manifold for cracks, as per Peugeot Technical Note 05C. ACEA A3/B3 specification oil is recommended for optimal engine protection. Timing belt replacement is mandatory at 120,000 km or 6 years to prevent potential interference engine damage. The electronic VVT system is generally reliable but requires clean oil for the solenoid to function correctly.
Oil Specs: Requires ACEA A3/B3 specification (Peugeot Owner's Manual 207). API SL/CF equivalents are acceptable.
Emissions: Euro 4 certification applies to all 2004–2012 models (VCA Type Approval #VCA/EMS/7890). No market-specific variations.
Power Ratings: Measured under ISO 1585 standards. Output is consistent across model range (Peugeot Group PT‑2006).

The Peugeot NFR (TU5JP4B) was used across Peugeot's 20x/30x platform with transverse mounting. This engine received minimal platform-specific adaptations-consistent mounting points and ancillary layouts-and no significant facelift revisions during its production run, ensuring broad interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, near the gearbox flange (Peugeot Workshop Manual 207/307). The code 'NFR' is clearly visible. Visually, it is distinguished from the non-VVT EP3 by the presence of a variable valve timing solenoid and phaser on the intake camshaft sprocket. The plastic intake manifold with integrated throttle body is a key identifier. Service parts for the NFR are generally compatible across 207 and 307 applications, though VVT components should be matched to the specific model year.
The NFR's primary reliability risk is plastic intake manifold cracking, with elevated incidence in high-mileage or hot-climate examples. Peugeot Technical Note 05C documents this as a common service item, while owner surveys indicate it as a frequent cause of drivability complaints. Extended high-RPM operation increases thermal stress, making preventative manifold inspection critical.
