Hey guys as you all know my car went under a serious build. I had the NGK plugs 1 step colder in the car and had them gapped to .30. Anyway what plugs do you think I should go with now after this build and also what should I gap them too? I am still thinking about sticking with NGK copper plugs as I have had NO problems with them!

 

You should go with 2 step colder imo, gaped between 25-35, i forgot what the plugs are called though.

 

.035 - NGK BKR7E
try it.....the .030 was real small.

or the ZEX plugs

 

Doc I have been hearing about these ZEX plugs. Do you have a part number for me? The BKR7E is what I have been using but those are only one step colder. What is the Part number for 2 steps colder?

Thanks for the quick responses! Cobalt SS.net FTW

 

With that list of mods I would definately use the Zex plugs. They are 2 steps colder. Zex part number 82003-4

 

Where are you able to order them from? I went to ZEX's site and typed in the PN but nothing was found. Could even find the chart on the application page.

 

82003-4 (thats for 4 plugs)
I think Intense sells them, I am checking now.

the stock plugs are ngk bkr 6e, one step colder is bkr7e, I would think two steps would be bkr8e....I dunno honestly.

Thats the ones, dude get the zex plugs!! They rock!

 

Kinda odd that every car on their site takes the same 82003 plugs.....
