What This Product Does
The coil transforms the battery's low-voltage electrical supply into the high voltage needed by the spark plug to ignite the mixture inside a cylinder. It is an ignition component, not a replacement spark plug.
Functions
- Produces the high voltage required for spark generation.
- Supplies ignition energy to the associated spark plug.

Symptoms of Fault
Possible signs include misfiring during acceleration, uneven idling, difficult starting, hesitation, increased fuel consumption or an engine warning light. Intermittent faults may become more noticeable when the engine is hot. Cracks or evidence of electrical tracking around the coil also warrant inspection.
Why Replacement Matters
A confirmed coil fault can interrupt spark delivery and cause recurring ignition problems. Replacement addresses the failed component, but similar symptoms can originate from worn plugs, damaged wiring, poor earth connections or injector faults. Inspect these related items rather than assuming that a misfire code proves the coil is defective.
FAQs
Must all eight coils be replaced together?
A diagnosed fault may require only one replacement. Review the condition and service history of the remaining coils before deciding whether further renewal is appropriate.
Can a coil fault appear only when warm?
Yes. Heat-related internal deterioration can produce intermittent symptoms, so testing should consider the conditions in which the fault occurs.
What should be checked before fitting?
Confirm the vehicle application and original reference, then examine the spark plug, electrical connector, wiring and earth connections. The cross-references above do not replace a vehicle-specific compatibility check.
