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.

These worked fine for my 2006 DTS. I had misfire on 7, traction control, slippery when wet and engine light error. Tip, use tape on wrench to avoid spark plug wrench separating from extension inside of engine block.

Hello, do these ignition coils come with the 'conversion kit'? I have a 2006 Cadillac SRX V8, and have the original design ignition coils. In order to use your 'second design' coils, I need this conversion kit.
Jack P on Jul 3, 2016
BEST ANSWER: This is NOT a conversion. Your vehicle either came with the 2nd design or it didn't. You cannot convert according to GM.
if this coil do not work properly can I exchange them or get a refund?
