Will it fit my Audi S3?
Petrol only. Gap, heat range and thread length are engine-specific — the wrong plug can misfire or, in the worst case, contact the piston.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Audi S3 spark plugs needs replacing
- Misfire or rough idle
- Poor economy or sluggish acceleration
- Difficulty starting
- Engine warning light, misfire code
Fitting it yourself
Usually one of the easier jobs — coil packs off, plugs out with a spark plug socket. Don't over-tighten into an alloy head.
Torque: Typically 20–30 Nm depending on plug/head — over-tightening can strip the thread.
