Where or how does one gap spark plugs? Can autozone do it for you?

TelosHedge

go one step colder than stock (8 range), iridium tipped for longevity, and resistor type.

NGK BKR8EIX is what i use. they give me no issues.

i dont know if you could even call it a tool...its a coin with different levels on its edge marked with the degrees.

but yeah. essentially what he said.

just gotta be really careful with the iridium tipped plugs because its easy to break them off with conventional gapping tools.

S2SEXY

which plugs are you using

Jacko

Not to mention a few F/I guys have lost there engine to those Iridium plugs

Just stay with the copper plugs and change them when you change the oil when I was S/C I used one step colder NGK stock #7173

I still have two sets that I haven't used if you want them bro there yours.

I'm going with 9's. only downside to running a plug too cold is they will foul a bit faster and it might be a tiny bit less fuel efficient.
run too hot of a plug? well that's a whole different story.
