Which NGK is the best???
Which one do you prefer?? I just put the NGK 3951 V-Power Plug; TR55's in mine and I am not sure I am sold on them yet. I took the NGK Iridium's off (because they had 34k on them) and think they were actually a better plug. I have already noticed a 1 mpg loss in the TR-55's and they just don't feel as responsive. Anyway just food for thought. What do you think and use?

I run TR-55's b/c the copper will produce a better spark, but it just won't last 100,000 miles. I change them every 20-30k or so... probably overkill. If you want to do it once and forget about it then roll with the Platinums. The Iridium plugs are supposed to be better for FI and Juiced applications.
Personally I doubt you'd feel any difference from two properly functioning pugs if all is working well... same with plug wires.

I have the AC Iridiums now put will go back with TR-55 coppers when I change them again.
