Used Nissan Almera Fuel Injector

Yes, but only on petrol-engined variants — fuel injectors are part of the petrol fuel delivery system and all petrol Almeras use multi-point fuel injection. Diesel Almeras use a completely different fuel delivery system (diesel injectors operated under high pressure) which are a separate part category entirely. If your Almera is diesel, search for diesel injectors rather than petrol fuel injectors.

The Nissan Almera ran in two distinct UK generations: the N15 (1995–2000) and the N16 (2000–2006), so a 2000 and a 2004 car sit either side of a generation boundary and are unlikely to share the same injector. Even within a generation, fitment is driven by the engine code rather than the year alone, so you should supply your engine code — found on your V5 or via a VIN check — to the breaker before assuming any cross-year compatibility. Confirm directly with the breaker whether the specific injector from a donor car matches yours.

Trim level does not affect fuel injector fitment — the injector is determined entirely by the engine code and fuel type, not by whether the car is an S, SE, or SVE. Two Almeras with the same engine code will use the same injector regardless of trim, so do not filter your search by trim. Bear in mind that a used injector sourced from a different trim car may carry minor cosmetic differences in wiring connector colour or bracket finish, but the injector itself should be the same unit.

The 1.8 petrol engine in the N16 Almera (2000–2006) typically uses the QG18DE engine code, and quoting this to the breaker is the most reliable way to ensure you get the correct injector. You can confirm your exact engine code from your V5 logbook or a VIN check, and it is also usually stamped on the engine block itself. Always give the breaker your engine code rather than relying on the engine size alone, as different codes can share the same displacement.

These are different generations with different engine families, so a direct swap across the N15-to-N16 boundary is not straightforward and the injectors are generally not interchangeable. The engine codes differ between generations — the N15 used engines such as the GA14DE and GA16DE, while the N16 introduced the QG-series engines — and injector specifications, connectors, and flow rates are matched to the engine. Confirm with the breaker whether any specific donor injector is compatible with your exact engine code before purchasing.

Fuel injectors on the Almera are not individually coded to the ECU in the way that some diesel injectors on more modern vehicles are, so a like-for-like petrol injector swap is generally a mechanical and electrical fit rather than a coding exercise. However, whether any programming or adaptation is required after fitting is something you should confirm with your fitting garage and with the breaker against your specific registration, as this can depend on the exact variant and any updates made during the production run. A qualified mechanic will be able to advise on any idle relearn or adaptation procedure needed after the injector is replaced.
