Drag Race Newbie
I am the "1" vote so far. They started out as a great product with my BKR7EIX plugs. I was first stage 2 with them and went K04. I had my K04 on the car and when I uninstalled the K04 and reflased back to stage 2 I had ridiculous amounts of misfires. Nothing changed other than a tune and turbo. I have been confused about that since then but I'm back on OEM coilpacks for now.
have you confirmed that one of the R8 packs was actually the root cause of the misfires and had itself failed?
