sup i just purchased some colder plugs by NGK stock no.1095 they are 7's.
dont know much about them, but do they come pregapped or do i gap them myself? if gapping them myself.. with should i gap them with?
im looking to push 6.8psi on a precision sc-61 turbo on this setup should yeld around 260whp with a built motor. i did do some research and these plugs should be fine for my set up right?

thanks

 

yessir..gap them at 28

 

what do you gap it with though? what does it come on pregapped? so gap them at 28? use feller guage?or what?

 

auto part stores usually have them next to the register the most common one is shaped like a large coin, you just slip it inbeween the prong(s) and the electrode thing then turn the "coin" untill you reach the desired #

 

thanks, yea tommorow ill drop by an kragan or something and gapp em..
the NKG ones i have at BCPR7ES-11
and they do not look like they are pregapped at all
so i should gap them at 28? which should it be?
im going for 250whp and 28 should be fine?

 

you heard the man 28, should be fine

 

ill gap them at 28
i just wanted to double check
thanks

 

i just bought a set off spark plug gapper today
i gapped them at .028 by pushing the ends to a hardsurface to bend
and now the .028 slides in and out with a slight touch from each end
