Vehicle Fit

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.

1st Time get Right auto Shop
The Product was actual the manufactory auto parts. I would truly recommend this shop to any and every body. The service was great with one exception. They need to do better on the correct time of delivery. Customer depends on delivery time especially when their auto is dismantle and waiting on their part. I feel that they should be a little more accurate, than less. over all they the best I seen online.
