OEM Part Number: confirm via engine code — aftermarket NGK 5960 / Bosch 0 242 236 565

Accuracy note: Covers the Seat Ibiza (6J 2008-2017) as listed in the UK aftermarket catalogues. Spark plugs are engine-specific — thread size (M12 vs M14), reach, heat range, electrode type (copper, platinum, iridium) and gap all change between engines in the same car, and the catalogue listings below cover every petrol engine in the generation without always saying which plug fits which. Match the plug to your engine code (on the V5C or the engine cover), fit a full set of the same type, and use the maker's gap and torque. Genuine numbers are shown only where a listing quotes one.

Petrol engines in this generation	1.0 75 HP, 1.0 TSI 95 and 110 HP, 1.2 60 and 70 HP, 1.2 TSI 86, 90, 105 and 110 HP, 1.4 85 HP, 1.4 TSI 140 and 150 HP, 1.6 105 and 110 HP, 2.0 115 HP; LPG 1.2 70 HP, 1.4 85 HP, 1.6 81 HP
Spark plugs (aftermarket)	NGK 5960 (nickel, 16 mm hex, M14x1.25); NGK 6893 (nickel, M14x1.25); NGK 2477 (iridium, M14x1.25); NGK 97153 (iridium, M14x1.25); NGK 96209 (iridium, M14x1.25); NGK 95262 and 5758 (platinum, M14x1.25); NGK 93231 (platinum, M12x1.25); NGK 96596 (nickel, M12x1.25)
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine plugs against your VIN / engine code
Fitment notes	All are 16 mm hex. Most 6J Ibiza engines use M14x1.25 plugs, with nickel for the basic petrol engines and iridium or platinum for the TSI turbo units; the M12x1.25 types are for specific variants, so confirm by engine. No change interval is shown.

Confirmed: A Genuine VW Group Coil Pack Recall Exists on Related Models — Seat Ibiza Spark Plugs

Worth checking directly with your dealer: VW Group has carried out coil pack recalls on various makes and models sharing this platform, with owners confirming a full set replaced free of charge on their Octavia and six coils replaced free on an Audi A4. If you're experiencing repeated coil failures, it's genuinely worth asking specifically whether an outstanding recall exists for your particular car, since this could resolve the cost of what might otherwise be an expensive repeat repair.

A genuinely frustrating, real pattern worth understanding if a coil keeps failing repeatedly: one documented owner went through around five ignition coils at roughly £30 each on the same engine, using the standard coil-swap diagnostic test each time to correctly confirm the specific failing cylinder — yet the same cylinder kept failing again within a couple of months regardless. This kind of repeat pattern, rather than being simply bad luck with parts, often points to an underlying root cause damaging every replacement coil in turn — a genuine possibility worth checking is a failed spark plug tube seal in the valve cover letting oil seep into the coil itself, gradually damaging each new coil the same way. If you're on your second or third coil for the same cylinder, checking the plug tube for oil contamination is worth doing before assuming you've simply had a run of bad parts.

Seat Ibiza Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems

The Seat Ibiza's spark plugs rarely fail dramatically; they just quietly degrade, showing up as a rougher idle or slightly blunted acceleration that gets blamed on other things. The part costs next to nothing, which paradoxically makes it one of the most commonly neglected items under the bonnet.

Before you buy: plug type and gap specification vary by engine size and generation. Always confirm against your VIN before ordering.

Seat Ibiza Spark Plugs: What They Do

On the Seat Ibiza, the compressed fuel-air mixture in each cylinder is ignited by the spark plugs, and their condition feeds directly into combustion efficiency, fuel economy and how smoothly the engine runs. Only petrol engines use them; diesels rely on compression alone.

Seat Ibiza Spark Plugs: Generations, Engines & Spark Plug Count

Diesel variants (TDI)	Not applicable — diesel engines use compression ignition and have no spark plugs at all
1.0 MPI/TSI (standard/entry trims)	Genuinely only 3 spark plugs — this shares VW Group's three-cylinder engine family, not a four-cylinder
1.5 TSI (Monte Carlo/higher trims, where fitted)	4 spark plugs — a genuinely different, larger four-cylinder engine from the standard car's three-cylinder unit
