Helping a buddy and i’m kinda scratching my head.  
The plugs we pulled out of the car are PFR6A-8, i took a look on the Champion website and it kick out a couple of NGK plug numbers: PFR6A-11 and another -11 number. What i’m scratching my head about it if the -11 plug numbers will run to hot considering we pulled -8 out of the engine. Any help from the skyline boys would be very helpful.

Thanks,  
Bubba

-11 at the end is 1.1mm

you prob want to gap it to the spark plugs you pulled out. -8 is most likely .8xmm

You pulled out a 6 heat range plug,the 11 indicates gap. Just get the same number plug, you can go with the -11 and just gap it down to .8. Sometimes you may be able to find a plug that doesnt even have the -11 at the end, again you would have to gap them your self.

Exactly -11 = 1.1mm gap

So just gap them to .8mm.

And try not to get platnium they are the shit in turbochagred applications

Stock gap is actually 1.1 mm. If you’re running more boost (1 bar) you’ll want to gap them to 0.8 mm.
