Ignition Coil for Holden Commodore VZ 2004 - 2007 V6 3.6L LE0 LY7 12590990 Plug Pack ensure a reliable voltage from the start and more ignition energy, so your engine starts and runs smoothly. Precise, corrosion-resistant connections that ensure excellent electrical connectivity, coupled with superior temperature and vibration resistance, lead to long service life. A coil-on plug (COP) ignition is a system where an individual ignition coil is placed atop a spark plug, found on the head of the cylinder and separating coils from exhaust heat. This makes it easier for spark plugs to receive voltage.

What does the ignition coil do?

• All ignition systems for modern petrol engines use ignition coils for the same basic function: to create the high voltage required to produce a spark at the spark plug

Are ignition coils worth replacing?

• Ignition coils are also recommended to be replaced if they show cracks, traces of arcing or other damage that may cause it to short out

 

What are the symptoms of a faulty ignition coil?

• Engine misfires
• Rough idle 
• A decrease in car power, especially in acceleration
• Poor fuel economy
• Difficulty starting the engine 
• Check engine light is on
• Exhaust backfiring
• Increased hydrocarbon emissions
• The smell of gas coming from the exhaust 
• Fuel leaks
