Praise for Ruthenium spark plugs! :)

[80stech]

I've been running Ruthenium plugs in the E53 (M54) for a while now and just switched over the wife's E83 (M54) and I have to say I am really impressed. Both electrodes are Ruthenium and narrow so waaay better as far as not shrouding. Easier firing which allows for running with the .044" gap as supplied for much better ignition, quick starts, and less stumble so all very positive. I'm not sure how long they will last (maybe someone else has been running them longer?) but I think they are worth it regardless

NGK ones for me, have had no issues as well
