The ignition coil transforms the battery’s low voltage into the high voltage needed to create a spark at the spark plug, essential for igniting the fuel-air mixture.
If you notice any of the following, the part likely needs replacement:
Engine misfire, especially under load or acceleration
Check Engine light with a misfire or ignition coil fault code
Rough idle or difficulty starting
Installation information
Bolts to the top of the spark plug (on coil-on-plug designs) or connects via a plug lead — always check the spark plug and boot for condition at the same time.
Frequently asked questions
On modern coil-on-plug engines, each cylinder has its own dedicated coil — a fault in one coil affects only that cylinder’s spark, causing a misfire isolated to that specific cylinder.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
