bummer..... check RPM outlet......i saw some on there for the 05+ 4.0s......or in that section anyway.

i have heard about people not being happy with them here lately though, so i'd check into it first.

I have the NGK iridiums gapped down. But they are better for Nitrous, for SC I hear you want race coppers, and this is the closest fit NGK has:


NGK V-power spark plug 7060 TR5-1 0.044

But I would trust Fazm's reccomendation over mine. I think the procharger ships with the V-Power plugs though.

Thanks Rygen... That's what I found as well.

Only problem is that I would like to go a step colder than the stock plugs. According to NGK -- the TR5-1 are 3/4" thread reach with an additional extension that acts like a insulator to protect the plug insulator from thermal shock and therby extending it to the stock .807"

Now I was told that I could use the TR6 - which is a step colder , but is 3/4" thread reach without the extension. Any thoughts from the crowd??
