Spark Plug reccomendation??

[gettocrx]

Just curious, which spark plugs should I use for my D16z6?
I tried Zex turbo plugs and a couple different NGKs.
But which ones works best for boosted D16z6?
Because a friend of mine reccomended NGK 1283 but it had hard time on cold start ups! another friend told me to use NGKs ZFR7F-11... But I want to see what most people use? also what should I gap it at?
Or maybe It's because I dont usually gap it?
Aight Thanks!

Id run an NGK-R7233-8
its an NGK-R plug
thats one step colder then what your running now.
gap it at like .44"

gap it at .44?! damn you could throw a football threw that thing

Turbocharged to 15psi, supercharged to 10psi, NA up to 12:1
NGK 7173 R5672A-8
Gapped to .020-.025

Turbocharged 15psi+, supercharged 10psi+, NA 12-13:1
NGK 7405 R5672A-9
Gapped .018-.022

Turbocharged 650+, Boosted with Nitrous, NA 13:1+(Race gas only)
7942 R5672A-10
Gapped .013-.020

These are non-resistor racing plugs. If you want to run a resistor type spark plug you can substitute the 8 and 9 plugs for the NGK Iridium 2668 (8) and 2669 (9).

.044 is 1.1mm and that is the recommended gap for a stock app. but cypher (as much as i hate to say it) is right. you should reduce the gap for higher hp apps.

I changed my plugs again with NGK 1283 (BKR7E-11) and gap @.35" car seems to be running better now.. I also found out the part# for ZFR7F-11 is NGK 2975. I'll try these next time since stock ones are the 2262 (ZFR5F-11). thanks for the info guys!
