My tuner had me put in NGK V-Power R5671A-8 (also says stock #4554 on the box if this helps) gapped at .35. im running 7 pounds of boost. Its supposed to be a pretty cold plug. Anyone ever heard of this plug number. Im just wandering if someone would recommend a different plug

currently i am running autolite 3924s.
the 39 is numbers put on the plugs with the long thread that the TFS heads use.

regular plugs are labeled autolite 23,24,25 etc.

25 is stock heat range, 24 is what i have and a step colder than stock. 23 would be 2 steps colder and going higher than 25 would be hotter plugs.

i run my 24s are like .033-.035 gap and all seems good now.... only making 7 psi at the moment with the setup.
