The Alfa Romeo AR 67302 is a 1,995 cc, inline — four, turbocharged petrol engine produced between 2023 and 2025. It belongs to Alfa Romeo's FireFly engine family, featuring gasoline direct injection (GDI) and dual overhead camshafts (DOHC). In standard tune, it delivers 195 kW (265 PS) and 400 Nm of torque, with hybrid — assisted variants reaching 210 kW (285 PS) in performance applications.

Production years 2023–2025 meet Euro 6d-TEMP emissions standards .
The Alfa Romeo AR 67302 is a 1,995 cc inline-four turbocharged petrol engine designed for compact and mid-size applications (2023–2025). It combines gasoline direct injection with twin-scroll turbocharging to deliver strong mid-range power and responsive throttle delivery. Engineered to meet Euro 6d-TEMP standards, it balances urban drivability with performance-oriented characteristics.

The Alfa Romeo AR 67302 was used across Alfa Romeo's 952/954 platforms with longitudinal mounting. This engine received platform-specific adaptations-tuned intake manifolds in the Giulia and revised exhaust routing in the Stelvio-and from 2024 received minor internal revisions to the high-pressure fuel pump system, creating service part distinctions. 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 AR 67302 offers strong performance and responsiveness, but early models (2023–2024) had reliability concerns, particularly high-pressure fuel pump wear. Later revisions (post-2024) improved pump durability, so well-maintained examples can be robust. Regular servicing and using high-quality oil (5W-40 ACEA A3/B4) significantly enhance longevity.
The most frequent issues include high-pressure fuel pump wear, ignition coil carbon tracking, timing chain tensioner wear, and intake valve coking. These are documented in Alfa Romeo service information bulletins and supported by workshop repair data.
The AR 67302 was primarily used in the Alfa Romeo Giulia (952) and Stelvio (954) from 2023–2025, both in 2.0 Turbo 265 HP and 285 HP (mild hybrid) configurations. It was not used in other Fiat Group brands in European markets.
Aftermarket ECU tuning is common on the AR67302 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 combined driving, the AR 67302 achieves approximately 9.1 L/100 km (31 mpg UK) in the Giulia. Real-world consumption varies with driving style; aggressive use can exceed 12 L/100 km, while careful driving may achieve 7.8 L/100 km (36 mpg UK). Mild hybrid variants improve stop-start efficiency.
Yes. The AR 67302 is an interference engine. If the timing chain fails or skips, piston-to-valve contact is likely, resulting in severe internal damage. Proper maintenance and timely inspection of the chain system are essential to prevent costly repairs.
Alfa Romeo specifies SAE 5W-40 synthetic oil meeting ACEA A3/B4 standards. Oil changes should be performed every 15,000 km or annually to protect the turbocharger and timing system. Using incorrect oil can accelerate wear in high-temperature components.
