Hyundai i30 Spark Plugs

Not automatically. The i30 sold in South Africa as FD, GD and PD, and N Line and standard derivatives differ in brakes, suspension and bumper mouldings — the badge on the boot changes the parts list, not just the trim. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.

The VIN is the single most useful thing — a photo of the plate is fine. Failing that, the generation code and the engine code off the block. The i30 ran as FD, GD and PD, so the generation is what narrows the search.

It follows the engine, not the model. A 1.2 Kappa and an older 1.4 MPi in what looks like the same car take different plugs, and the T-GDi engines are different again. Check the handbook or a parts catalogue against your engine code before ordering — the wrong heat range causes exactly the misfire and fouling you were trying to fix.

Standard copper plugs want changing roughly every 30,000km. The iridium and platinum plugs fitted to newer i20, Accent and Creta models run 60,000 to 90,000km. Your handbook has the interval for your engine; we would inspect at every major service regardless, because plugs read the engine's health better than most things you can look at for free.

Rough idle, hesitation when you accelerate, economy sliding, a check engine light and a misfire code on one cylinder. Pull one and the evidence is right there — worn electrodes, black soot or oil deposits. Fresh plugs restore smooth running immediately, which is what makes this such a satisfying job.

NGK plugs for Hyundai range roughly R19 to R399 each depending on grade, and you are almost always buying a set of four. Request a free quote with your engine code and we will include fitting — coil-on-plug designs add labour, so the parts price on its own understates the job.

They are the most common cause, so start there rather than at the coils or injectors. What the old plug looks like is worth reading before you buy anything: oil fouling points at valve stem seals or piston rings, dry black soot points at a rich mixture or a faulty sensor. In both cases new plugs alone would only postpone the problem.
