Re: Best plugs for 4.7?
Puffin:

X2 on the OEM Champion copper plugs. If you want, you can run platinum but I recommend the platinum version of the oem copper which is a RC12PYP IIRC. I ran a set of these in my 01 4.7 for 50k, and they looked like new when I removed them.

I THINK the OEM copper is the RC12MCC4 which are cheap, and do a good job.

YMMV Don
