Advice regarding quadfire plugs?
I just got the 60k mile service done on my Hyundai, and asked the stealership to put in quadfire plugs. They balked, telling me that they run too hot and installing them would nullify my warranty (I say bull...).
When I first bought my Benz 7 months ago, I looked at quadfires, but a local Mercedes guru told me the temp range isn't that great and that quadfire plugs aren't recommended for colder climates.
So what's the skinny here? I put qads in a friend's Camaro, and the car had a NOTICEABLE performance increase, so why not a nice, older Benz?
