Re: Diamond Fire E3 spark plug
Yeah, well I'm old and scared of new things....
just recently got used to these newfangled cordless phones!
Seriously, I prefer stuff I KNOW works over untried gimmicks and I have used platinum so I feel fine recommending them to others.
Never used Iridium yet, but if GM uses them, it's for a reason.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
