E3 Spark Plugs
Just wondering if anyone has tried these spark plugs in there MB, 190 or other? The idea of these "improving gas mileage" is appealing. Mine is a '93 190E 2.6
Thanks for any help!

I had reviewed their website, but I was looking for anyone on here who had actually used these on their Benz. There are testimonials on their website, but it's not like they are going to put up bad reviews.
Sorry for rubbing you the wrong way and posting a newb question.
