OEM Part Number: confirm via engine code — aftermarket NGK 94833 / Bosch 0 241 245 673

Accuracy note: Covers the Seat Ateca (2016-) 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 TSI 110 and 115 HP, 1.4 TSI 150 HP, 1.4 TSI 4Drive 150 HP, 1.5 TSI 150 HP, 1.5 TSI 4Drive 150 HP, 2.0 TSI 4Drive 190 HP
Spark plugs (aftermarket)	NGK 94833 (platinum, 16 mm hex, M14x1.25); NGK 95929 (iridium, 0.8 mm gap, M12x1.25); NGK 94224 (iridium, 0.8 mm gap, M12x1.25); NGK 97124, 93231 and 97861 (platinum, M12x1.25); Bosch 0 241 245 673 (0.7 mm gap, M14x1.25); Bosch 0 241 245 677 (0.65 mm gap, M14x1.25); Bosch 0 241 145 525 (0.75 mm gap, M12x1.25); Champion OE273 (iridium, 0.75 mm gap, M12x1.25)
Genuine (OE) numbers quoted	Kamoka 7090007 cross-references 06K 905 601 B
Fitment notes	Both M14x1.25 and M12x1.25 plugs are listed, all with a 16 mm hex; the M14 type (Bosch 0 241 245 673 and 677, NGK 94833, Champion OE246) matches the 06K 905 601 B family used on the 1.4, 1.5 and 2.0 TSI, while the M12 types suit the smaller engine variants, so confirm by engine. No change interval is shown.

Confirmed: A Genuine VW Group Coil Pack Recall Exists on Related Models — Seat Ateca 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 Ateca Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems

On the Seat Ateca, spark plug wear tends to creep in quietly — idle gets a little rougher, throttle response softens slightly — the kind of symptoms that get blamed on almost anything else under the bonnet. Given how cheap the part itself is, it's an easy one to put off for longer than makes sense.

Seat Ateca Spark Plugs: What They Do

Inside each cylinder of the Seat Ateca, spark plugs ignite the compressed fuel-air mixture, and their condition has a direct effect on combustion efficiency, fuel economy and how smoothly the engine runs. Petrol engines can't function without them; diesels don't use spark plugs, relying on compression alone to ignite fuel.
