I have a 2008 gt with a cai and bama tune running 93 octane. Any recommendations for a good set of plugs. Ive got my eye on the ford racing 0degree but everyone I ask is running nitrous or supercharged. Any reccomendations?

If you want to change the spark plugs out, stick with the stock heat range of 5. No need to run anything cooler unless you're supercharged or nitrous injected. You'll actually loose efficiency with a colder plug on a N/A GT.
I honestly would stick with our stock plugs if they're in good shape!
