Second Hand Nissan 370Z Glow Plugs

No – the Nissan 370Z is fitted exclusively with a 3.7-litre naturally aspirated petrol V6 engine (VQ37VHR), and glow plugs are a diesel-only component used to pre-heat the combustion chamber on compression-ignition engines. The 370Z was never offered with a diesel engine in any market, so glow plugs were never fitted to any variant of this car. If your 370Z has a starting or cold-running issue, you are most likely looking for spark plugs, an ignition coil, or a related petrol ignition component instead.

Almost certainly yes – glow plugs only exist on diesel engines, and the 370Z has always been petrol-only, so no breaker will ever list glow plugs for this car. What you probably need are spark plugs (the petrol equivalent) or possibly ignition coils, which are common service items on the VQ37VHR engine. Search for '370Z spark plugs' or '370Z ignition coil' and you should find what you are after.

For ignition components such as spark plugs and coils, trim level makes no difference – all UK 370Z trims (including GT, GT Edition, and Nismo) share the same VQ37VHR 3.7-litre petrol V6, so the engine parts are the same across the range. The Nismo variant does have some engine tuning differences, so it is worth supplying your exact engine code and registration to the breaker to confirm the correct spark plug or coil specification. Trim level affects cosmetics and suspension tune, not the basic ignition hardware.

The 370Z ran from 2009 through to around 2021 in the UK, with a facelift introduced for the 2013 model year that brought styling and equipment changes. The VQ37VHR engine carried through the entire production run without a fundamental change, so spark plugs and ignition coils are generally consistent across the range, but you should confirm with the breaker against your registration and engine code before buying. Ancillary mounting details can change across a facelift boundary and the breaker will be best placed to verify compatibility with your specific car.

On a petrol engine like the 370Z's VQ37VHR, the components that do a similar job to glow plugs are spark plugs and ignition coils – they provide the ignition energy that a diesel glow plug provides as heat. A misfire, hard cold start, or rough idle on a 370Z is most commonly traced to worn spark plugs or a failing coil pack, both of which are available as used parts from breakers. Give a breaker your registration or engine code and describe your symptoms and they should be able to point you to the right part.
