Cheap Hyundai Ioniq Glow Plugs

No — the Hyundai Ioniq was never sold with a diesel engine in the UK, so it has no glow plugs at all. The Ioniq range used petrol-hybrid, plug-in hybrid, and fully electric drivetrains, none of which use compression ignition and therefore none of which require glow plugs. If your car is misfiring on cold starts or struggling in cold weather, the fault is more likely related to the spark plugs, ignition coils, or hybrid battery system depending on your variant.

Almost certainly not, unless there has been a mistake in the quote. The Ioniq has no diesel engine variant, so glow plugs are not a part that exists anywhere in this model's range. It's worth double-checking the part being quoted — the supplier may have misidentified the fault or the vehicle, and spark plugs or ignition components are far more likely to be what's actually needed.

No — the combustion engine in the Ioniq Hybrid and Plug-in Hybrid is a petrol unit (a 1.6 GDi), which uses spark ignition rather than compression ignition, so glow plugs simply don't apply. Glow plugs are a diesel-only component, used to pre-heat the combustion chamber in cold conditions on diesel engines. For cold-start issues on an Ioniq Hybrid, spark plugs or the high-voltage battery health would be the correct areas to investigate.

For the petrol-hybrid Ioniq (2016 onwards), the relevant ignition components are spark plugs and ignition coils — these are the parts that handle combustion, not glow plugs. If you're sourcing used ignition parts from a breaker, your engine code (found on your V5 or via a VIN check) is the most important detail to supply, as it confirms exactly which spark plug specification your engine requires. The fully electric Ioniq Electric has no combustion engine at all, so neither glow plugs nor spark plugs are relevant to that variant.

Trim level makes no difference to the ignition system on the Ioniq — the Ion, Premium, and Premium SE all share the same 1.6 GDi petrol hybrid engine, so spark plugs and ignition coils are determined by the engine code, not the trim. When contacting a breaker, give them your engine code and registration rather than the trim name, as that's what they'll use to confirm the correct part. Trim only affects cosmetic and comfort features, not mechanical components like these.
