Ignition coils running? I'm running heat 8 iridium BKR8EIX on stock ignition, trying to make sure the R8 coils will make a good electrical connection with these... Something I didn't research ahead of time. The seal on the R8 coil runner tube wants to squeeze these plugs out. I will be machining a plate to hold them in but more concerned with the electrode making good contact. The OEM looks like it has a floating electrode tip but the R8 looks like it doesn't but I really can't tell. Still in the middle of round 2 build so can crank right now..
