Wat kind of spark plugs r good for muh 94 z28...thanks

 

I run the stock ACs from the dealer and I run the gap out to .050" using an MSD 6A box...lots of people on this board like the NGKs...You didn't tell us anything about your combo...stock, modified, blower, nitrous, etc...those factors would be helpful...

well iahve an slp intake...slp loudmouth exhaust...slp headers n thats bout it

 

I would use the stock ACs with your set up, but they are more $$$...Its really just a preference, though...Do a "search" on this board and see what others have said...

 

I stick with NGK TR55's now. I've tried every plug on the market in my vehicles, except for, oh I can't remember who made them but they were like $10 each which I'd no way in hell pay for. The NGK's are cheap and effective.
