After replacing my plugs i found that gapping them with the classic little puck tool was not very accurate especially since were talking down to the tenth decimal place. Is there either a better tool out there or just a better method other than trying to line up the plug on the puck and jamming the metal arm down into it...

 

Get one of these gappers:

Far more accurate, and no chance to mess up.

 

what do you actually bend the metal arm on though?

 

You bend the groud like you open a bottle on the side tab. That's the only real way to do it that I've seen, and I've seen some ways.

 

the little disc is very accurate if you know how to use it right, or get f6dtc's and not worry about gapping at all

 

off topic but, the F6DTCs , are they stock temp... if so , what are the non-gappable equivalent t a cooler plug like the NGK BRK7E's?

is there an F7DTC?

 

7's are colder than 6's.

 

doesn't seem to matter with this plug. f6dtc's work in everything from stock a4's to Mike's 600+whp a4 to 034's vr6-t swap (running 40 psi)

 

There are gapping pliers as well. The picture shown, that tools works good. I simply use the old school disc, and it works well. Even if you are off a .01, it wont matter. (I dont see how you could, it is literly idiot proof.... I thought)
