Service Life of Iridium ( IK20 ) plugs in S4?.....
I know some report or worry of electrode failure in Iridium plugs. I think that may be a result of improper gaping or handling during install.
If that is not a worry, what is the service life of these plugs? Less than Double Platinium? Same?
I have 40,000 miles on a set of IK 20s. Car runs like new! Change 'em? Or go another 10Ks or so??????
