Review on NPAUTO Ignition Compatible Chrysler Challenger by David Dortch

. I only gave them four stars because I had to disassemble a few of these to get the loading spring sticking out enough to make contact, but I ended up paying the same price for these as I would pay for one of the OEM coil packs , so I really won't end up complaining about some minor installation issues. Anyone with the mechanical ability to change coil packs and connectors can easily make the necessary adjustments to this product. I was going to wait a while before doing a review to make sure they don't have a crazy sales law, but as long as they perform just like the OEM coils before wearing out completely, they were a great deal. I have no complaints this is a good product at a good price. Thanks very much!
