I've searched for the past two days and haven't really came up with a definitive answer on the best place to find a set of Coils for my 04 Cobra. I'm getting a stumble in boost that has started about a week or so ago. I'm going to change out the copper TR6's with some Iridium TR6's and install new coils since these two areas are the most common areas to look from what I've read. Long story short can someone point me in the direction of a place to not have to pay $350-$500 for a set? :beer:
