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.

Ignition Coil Set
The set of 5 I Coil Packs I ordered were about 50% less than the Auto parts stores. They were a perfect fit- right down to the OEM connectors, etc. Runs great- fixed my ignition "miss" issue.

1 Comment: I also purchases Spark Plugs but they only came in sets of 4 and I needed five. No biggie though. I bought 1 locally and on the road again.
