Vauxhall Zafira Glow Plugs Replacement Parts

Glow plugs are exclusively a diesel engine component — they pre-heat the combustion chamber to aid cold starting, and petrol engines do not use them at all. If your Zafira is a petrol model (for example the 1.6, 1.8, or 2.0 turbo petrol Z18XE, Z18XER, or Z20LET codes), glow plugs are not fitted and you will not find them on your engine. Only diesel-engined Zafiras — such as those running the 2.0 DTI, 2.2 DTI, or 1.9 CDTi — will have glow plugs, so confirm your fuel type before searching.

The Zafira A ran from 1999 to 2005 and the Zafira B from 2005 to 2014, and while both generations shared some diesel engine families, fitment of glow plugs follows the engine code rather than the generation. A 1.9 CDTi in a late Zafira A and an early Zafira B may share the same plug, but you should confirm the exact engine code — found on your V5 or via a VIN check — with the breaker before purchasing, as ancillary component specifications can vary within the same engine family across that production boundary.

Trim level makes no difference whatsoever to glow plug fitment — Club, Design, Elegance, and any other Zafira trim all use the same plugs if they share the same engine code. Glow plugs are purely an engine-driven specification, so focus entirely on matching the engine code rather than the badge on the tailgate. You may find minor cosmetic differences between stripped-out breaker cars and your own vehicle, but the plugs themselves will be identical across trims on the same engine.

A diesel Zafira will have one glow plug per cylinder, so a four-cylinder engine such as the 1.9 CDTi has four plugs, while a five-cylinder diesel would have five. Breakers will often sell the full set stripped from a donor vehicle, which is generally the better option since plugs tend to age at a similar rate and replacing the full set avoids repeat labour costs. Confirm the cylinder count for your specific engine code when contacting the breaker so they can supply the correct quantity.

The Zafira B ran from 2005 through to 2014, with a facelift in 2008, and the 1.9 CDTi engine code is the key factor here rather than the model year. If both cars share the same engine code — for example Z19DTH or Z19DTJ — the glow plugs are very likely to be compatible, but you should confirm this against both registration numbers with the breaker as there can be minor specification changes within a production run that are not always reflected in the engine code alone. Providing your exact engine code from the V5 gives the breaker the best chance of matching the right part.

Glow plugs follow the engine, not the model, so if a Vectra C or Astra H shares the exact same 1.9 CDTi engine code as your Zafira — such as Z19DTH — the plugs from those donor vehicles are generally suitable. This is worth knowing because breakers may have a wider stock of Astras and Vectras than Zafiras, potentially giving you more choice and better pricing. Always quote your engine code to the breaker and ask them to confirm against both vehicles' specs before committing to a purchase.
