Very close to pulling the trigger on an APR tune (I'm at 35k miles). I've seen the plugs and coilpacks mentioned but never seen any specific info about what plugs and coilpacks. Any additional info to help with the acquisition would be appreciated.
Audi "red-top" coils are what you are looking for, and you can get them from any reputable vendor. I got mine from modded euros. Those guys rock, and have always treated me well. The spark plugs that I have in my signature are also a very popular option. NGK BKR7EIX, I believe. Can't remember where I got mine; either HS Tuning or Urotuning.
My two cents: plugs and coils are a must. I have read a lot of stories about people blowing the stock black coils after getting tuned, and it is very scary, especially at highway speed, or in the middle of a WOT pull. Not necessarily dangerous for you, or horrible for the engine, but you wouldn't want to drive very far if it were to happen. HS Tuning did bench testing with the red top coils, and determined that they do indeed make a difference, and are not just cool-looking. Hope that helps
