Hrmm... Should I just switch to 3923/5224. Bernd: With the advanced
timing of the mike leach computer (29 degress instead of the factory 23)
should I still run a cooler step plug?

Thanks
william

I'm not one to side with the dealer on this one, but if you look at the
posts on the 4.7L and Bosch +4 "issues", you'll notice complaints on
mis-firing, poor idle, and performance loss. While it's too random to
point a finger on...don't leave it out of the loop as the +4's are known
for causing problems.

BTW: The standard Autolite 5224's also meet OEM specs.

Riiiiight. I guess they can't handle the pressues of turbochargers. Best
plug I ever used in my 740T. Your dealer is shining you on. In fact, you
may wany to point out Bosch plugs meet OEM requirements-see how his
story changes.
