The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition. In engines like this with one coil per cylinder you can diagnose a coil by putting a timing light on each one to make sure it is lighting the light consistently.

Works as well as OEM
I have to say, I was skeptical of this item at first b/c of the price. These go for $70 a piece at O'reillys, so to buy a whole set for $60! Come on!!!.... But, I did it...installed them...and I have to say...I'm like a champ! Car is back to running great! Thanks!
