Ordered 6 of these along with the conversion kit for my '02 A6 2.7T and this upgrade is just what I needed. I knew I had one bad coil, but this not only has obviously fixed that problem, but made it run so much smoother than before as well. Great upgrade!
Not only that, but shipping was incredibly fast. Ordered it on the weekend, and they still got it to me the day before Thanksgiving. I didn't expect that.....awesome surprise. Thanks 034!
