I have them on my SRT4. It developed a bad miss after a week. I am $100 poorer.

In science, we usually go by the maxim that unusual claims require unusually solid data to support them. Those proposing something ordinarily bear the burden of proving it.

I see nothing to really support these things. Worse, the claims are very similar to claims made for "new" "improved" spark plugs over the last 50 years or more - none of which have panned out.

But, if you would like to spend $300 for your own testing, then by all mans, go ahead.

Get back to us after you've tried them and gotten your data/facts.

One negative experience so far.......
