Cheap Nissan Micra Glow Plugs

Glow plugs only exist on diesel engines, and the Nissan Micra has been an overwhelmingly petrol-only car throughout its UK life – the vast majority of Micras you will encounter have never had glow plugs fitted. If your Micra is petrol, the cranking aid you are looking for is spark plugs, not glow plugs, and that is almost certainly what you need to search for on Findapart.

Almost certainly not, because virtually every UK-market Micra runs a petrol engine and petrol engines do not use glow plugs at all. Cold-start problems on a petrol Micra are far more likely to point to spark plugs, an ignition coil, a faulty coolant temperature sensor, or a fuel delivery issue – those are the parts worth investigating and searching for here.

It is possible if you happen to own one of the very rare diesel-engined Micra variants, but these were extremely uncommon in the UK and if you are unsure whether your car is diesel you should check your V5C, which will state the fuel type, or run a VIN check. If your V5C confirms petrol, the advice to replace glow plugs does not apply to your car and it is worth going back to the garage to clarify what they actually found.

Trim level – whether your Micra is an S, SE, Acenta, Tekna, or any other grade – has no bearing on whether glow plugs are fitted; what matters entirely is whether the engine is diesel. Because diesel Micras are exceptionally rare in the UK, the safest first step is to confirm your fuel type from the V5C before searching for this part at all.

For a petrol Micra, the equivalent of a glow plug is a spark plug, and you should also consider searching for ignition coils if the engine is misfiring. Both parts are widely available from UK breakers on Findapart and are specific to your engine code, so having that code to hand – found on your V5C or via a VIN check – will help breakers quote you the correct item quickly.
