This Ignition Coils 12590990 is 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.

Features:

• Coils 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.
• Properly performing ignition coils can provide increased ignition energy, lower fuel consumption, and reduced exhaust emissions for your vehicle.
• Ignition coils are built to achieve or exceed OE specifications and are known industry-wide for their reliability and performance.

 

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
