I've seen the electrodes fall out of them in running engines for absolutely no reason.........which are bigger than the quench distance in most engines.

We get a lot of cars where people install them there selfs and can not figure out why it started missing. Ocasionally we see that with autolites or champions and I have only seen an NGK do that one time even after working at a honda dealer for 3 years where they are factory installed so I use NGKs, not platniums just the regular old NGK. I am not causing global warming, I am just trying to hold off a impending Ice Age!

We've been using NGK's with mixed results so we are now going to try the Autolites. Splitfire plugs are a gimmick based on cleavor advertising. They are no better and in some cases worse than the cheap plugs. Platinum and double platinum hold up better in newer cars but offer no better performance.

The Nickens test claims an improvement and you say you say you saw it go the other way. FWIW I'm with you and would trust the AR plugs over Brisk. On our deal we just want the plug to fire. 5 or ten extra HP out of the plugs means diddily squat to us. We've had a few dead holes for no apparent reason(nothing else wrong) over the course of this season and we were told that guys in the know use the AR plugs over the NGK's we were using. The next race we'll have the AR's on board.
