I bought a set of NGK Laser Iridium ILTR5C11 plugs. This is prolly a dumb question, but do i keep them at the gap they come with (.044"), or do i gap them to the stock gap(.040"). Also considering the mods i have is it better to have a smaller or bigger gap?

 

i think you are going to get some different answers here. i myself am not certain about this kind of thing. but from what i have gathered the best plugs are the stock plugs. so a change in plug brand would be useless. but if they work, more power to you man. just saying that i will be running stock plugs for the life of this car.


back to the topuc, i still don't know...

 

i dont regap them unless a problem occures.

 

.044 to .040 is perfect for na stock cars. Your fine keeping them where its at. You really just need to worry about gap when you go FI or nitrous.

 

what about higher powered cammed n/a cars lol, what would a good gap for us be??

 

ha nawe i think is so funny its like theirs diffrent answers for n/a guys, f/i guys,nitrous then theres you lol

 

you will never notice a difference between .040 and .044... the proper way to gap iridium plugs is to measure with a tool, then adjust the plug with a small pair of needle nose pliers..

 

ya...i just dont ahve a normal n/a car hahaha

 

hey more power to you ) i dont even know what your next mods can be besides tires and suspension...right like is teir anything else your gonna be doing to your engine? sorry for off topic in post

 

I'd say you want to be at .040

 

build the bottom end of the engine lol

 

Your fine at .040 dude. Get new springs and spin to 7500, and eventually some 11:1 pistons if you want to go high compression. Should make for an even faster car.

 

your next mod should be a stage 1 or stage 2 clutch im sure thatll help nwae

 

i doubt he'll need it, im sc'd and my stock clutch it holding fine...hes making ~190whp...he should be ok

 

yea I'm goin on 50,000 miles on my stock clutch...

 

Update: I gapped them at .040". It runs perfect! My air/fuel ratio is even more stable/efficient. And like NWAE said, "I am not a regular N/A car"!!! Me and him and a few others on this site are running cams. Which is why I was wondering what gap to stick with, anyhow i just did the stock gap, which is .040"

 

its holding fine, but if it ever goes its getting replaced with not stock lol, no point in going in there and not putting somethign better in lol

next step is a spare motor built from the ground up for total n/a
