E3 premium diamond fire spark plug?
I'm looking to put new spark plugs in my 5.7L hemi. I am looking at these E3 diamond fire plugs and just thought I'd ask if anybody else uses these plugs and are they any count.

Heard of them fouling out a lot. For plugs, go with what the engine was designed for, or at least carry a full set of OEM plugs with you if you do go with the fancy aftermarket ones so you are only stranded for an hour or two if they don't work. Also heard they work great in lawnmowers... I wouldn't touch them.

Stick with factory specified plugs. Your just wasting money on a marketing gimmick that is not going to help and may cause more problems. A fancy name does not always make for better.
