KA-T guys, What spark plugs do u run?

[Ghst 01]

Looking to get the project done this week.... i've heard that when u boost ur car it's better to run colder plugs... I was wondering what are sum of u running? and is it necessary to change them?

[Mr. Spool]

I am not running colder plugs, infact I asked the exact same question and nobody knew the anwer. I have been playing around with different plugs and gappings lately and I found that 42degrees seems to work pretty well.

If anybody has found this to be to the contrary let me know.

BKR7EIX-11, pretty sure they are the Iridium version if not its the standard with the 7 heat range.

[Mr. Spool]

what will these do?

This will give you more info about colder spark plugs. (click) (http://www.sentra.net/tech/sparkplugs.php) I think the rule of thumb was supposedly to go one step colder per 100hp increase to the engine.

NGK BKR6E11, gap = .037

I tried BKR7E11 but they were too cold(misfire/fouling) for my application..

[Mr. Spool]

how does the .037 work for you. cant you make it that small if you are running abit lean.

ND ik27 plugs work for me. gap at 28 - 30

I'm running NA z32 plugs, one step colder than stock (and one step colder than TT plugs), gapped to .025.

[Mr. Spool]

what kind of boost are you running and did you happen to notice a difference of the .042 gapping that ngks come with.
