Signs your Seat Leon 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.
