What inches or millimeters should I gap the spark plugs to if I'm running stock boost and stock turbo?

How should we gap according to our mods? like i want to get bigger injectors and a bigger turbo, more psi, do i need to gap more or less? right now im running stock set-up but at 10 psi. do i need to adjust the gap?

motegineon

well from my knowledge stock should be .032

some mods/up the boost a little .030

good amount of mods/15+ boost .028

im running 16psi with all boltons/larger injectors/t28 and i run .029

Okay cool. also what is a goo spark plug to use? I've heard different reviews about what are the best plugs to use. Im actually using bosch platinum +2 that dont require gapping but i want to switch to a good plug that i can adjust the gap on.

motegineon

i use ngk-bkr7

The iridium ones? cause i saw the bkr7e then the bkr7eix. since it's colder how would that affect the way my motor runs? and would it be good for my current set-up? (10 psi, stock turbo, fmic, 3 inch exhaust)

motegineon

no i dont run iridiums, just the e's

Cool. Thanks. i'ma pick some up and try them out. can you tell how they perform compared to any other plug?

motegineon

naw, thats all ive ever ran in my car, although I can tell you proper gapping makes a world of a difference..

oh i believe you. i had an rb and i didnt set the gap to the right spec and i couldnt go past 4k and it would studder horribly. Thanks, i appreciate the advice.

Alright here's the thing, I bought these spark plugs quite some time ago when I was just buying up parts for a intended swap, some of these parts I didn't do my research on and that brings me to ask this question. You guys say that my stock plugs should be gapped to .032 well I've checked them all and these NGK Iridium plugs are gapped to .042. The part number is BKR5EIX-11. I was told that you shouldn't try to re-gap Iridiums so should I try or just drop 'em and get the right plugs?

motegineon

ok well i wouldnt run a 5 anyways, u should be running atleast 6 but most people run 7, like myself..

also yes i get the 11's too and i regapped mine downward to .029 with no problems whatsoever..also i dont run iridiums, sr's should have there plugs changed atleast yearly anyways..just the plain bkr7es-11 work fine for me..also there only like 2 bucks or something a piece. i just order the box of 10 from advance auto parts that way ur set for your next change and you have 2 spairs just incase
