Details

Replace the spark plugs when the engine misfires, idles roughly, or fuel consumption rises, since worn plugs produce a weak spark that reduces combustion efficiency and overall performance.

• Replacement sign: Engine misfires, rough idling, hard starting, and noticeably higher fuel use.
• Approximate lifespan: Roughly 30,000 to 100,000 km depending on plug type and driving conditions.
• Install requirement: Requires a proper spark plug socket and correct torque tightening by a qualified technician.
