I was just wondering if I still need to replace my plugs and with what kind? Also since there's only 91 octane here in Cali, will that be okay while running NOS? Thanks in advance for the replies.

 

I believe you're going to want to go with a spark plug that's one heat range colder than stock, and with shorter gap.

Above all, make sure that the spark plugs you use are not platinum tipped.

 

thanks... but how bout octane ratings? Is 91 octane okay

 

91 should be ok with most nitrous setups. Check out http://www.nosnitrous.com/HiOctn/ProdLine/...techcorner.html for more info.

 

John, if you ever go racing or want to use race fuel there is a 76 station in Pasadena that sells 100 octane fuel. It is pricey. I believe that 91 octane is fine as long as you do not use nitrous for extended time periods.
