IGNITION COIL

An ignition coil is a key component of a petrol engine’s ignition system. It converts low battery voltage into a high-voltage pulse required to create a spark at the spark plug, igniting the air-fuel mixture inside the cylinder.

Modern engines use individual coil-on-plug units or multi-coil modules. The ignition coil operates in coordination with spark plugs, the engine control unit, and crankshaft and camshaft position sensors.

Common failure symptoms include engine misfires, rough idle, reduced power, increased fuel consumption, and check engine warning light activation. Prolonged driving with a faulty coil may damage the catalytic converter.

Our catalog includes ignition coils for many vehicle brands. Genuine factory ignition components, reliable aftermarket replacements, and tested used coils without overheating or insulation breakdown are available.

Used coils are inspected for housing cracks, electrical breakdown marks, overheating signs, and stable spark output.

Selection is based on VIN number, engine code, ignition system type, and part number. Replacing a faulty ignition coil restores engine smoothness and performance.
