I bought a set of the zex spark plugs to run with my nitrous setup but after reading about a guy on here blowing his #4 cylinder and finding out it was the zex spark plug that did it im a little worried about running them i havent gotten around to putting them in yet but if they are going to screw up my engine i will go buy some other ones. So has anyone else used these spark plugs with there setups and had problems?

 

Depends on what the heat rating is compared to the stock plugs.
Might be colder might be warmer. Besides Zex plugs are just rebranded NGK's if I remember right.
Best bet is go with some NGK's that way you know what rating your getting. The stock is BKR6E. After Stage 2 most go to BKR7E. So one step colder from that is BKR8E. And I run BKR9E's for my nitrous setup. Let me clear thou after BKR7E they only come in Iridiums so that part numbers are BKR8EIX and BKR9EIX.

I'd return the Zex plugs and get NGK's.

 

yea thats what im thinking about doing do you have to special order the ngk's or do you think local parts stores might carry them

 

I got mine from Advance Discount. But any part store should have them. They may have to order them but usually comes in in a day.

 

not every place caries them but i know that napa does

 

yea i figure they might be able to get them faster then i could ill look into that thanks man what size shot you running

 

Just a 55 for now. Down the road might get forged pistons and up the shot to 100.

 

yea id like to do that also is forged pistions all you need to run a 100 shot i was going to try and do sleeves to and probably valves and springs all that good stuff to while it was apart maybe a valve job to but i havent looked into it that much since it will probably run at least 1000 probably more when all is said and done which i dont have right now.
