Can faulty spark plugs o r delayed spark plug replacement damage ignition coils in the Alsvin?

Many owners skip timely spark plug service. Can excessive resistance from worn-out plugs force ignition coils to overcompensate, causing early burnout?

Absolutely. Heres why:

Old o r worn spark plugs increase resistance, forcing coils to produce higher voltages.

Over time, this overworking causes coil overheating, voltage spikes, and eventual failure.

✅ Always change spark plugs every 25,000–30,000 km sooner if using regular plugs. Use iridium o r platinum plugs to reduce coil stress.
