Spark plug
Did sum searching nvr found anything. Just would like to find out what is the best spark plug.

im running a Sr20DET Greddy air filter, nismo fpr, walbro 255lph, Lightened flywheel, UR pulleys

I know alot of people are using the NGK iridium 7 heat range
(if im not mistaken)

thats what most opt for is the 7 heat range plug, not sure exactly what all material they are made in, im running ngk bkr6's copper plugs for now, i will be putting in the 7's soon,

Any NGK7 will work fine. If its a stock DET you can even get away with 6's

ok well it isnt gonna stay std for long. In this year going to be GT3076R and 25psi boost

ngk 7-8 are good

P/N BKR7E, i use standard plugs because some ppl complain about the platinum tip.

Gapped to .030-.035

bkr7e. go to advanced auto. autozone doesnt carry them. i like to gap mines at .027

^ i couldnt gap my 7's any larger than .28 without the boost blowing out the spark

as far as right now im running the 6's at .32 and i dont have any misfire issues at 17psi, drops to 10psi by 5500rpms, i will be putting a set of 7's copper in when i recieve them from my friend. I wont use the iridiums, i dont like the thin tips. with the bigger tip you have more chance that the plug will fire under boost, plus im not spending 40.00 on plugs that im still gonna have to change out pretty often. I usually put about 10k miles then change them, just a safe assurance.
