Anyone have any plug recommendations for my set-up. AFR 210s 9.5cr 10-15psi. I need a good starting point. I was running tr6's with my stock headed nitrous car but I read AFR's call for different plugs. Not sure if it matters but I'll be running a little water injection.

thanks in advance

 

My app... 97ss 383ci Procharged ~14psi, afr190 heads MM6. I run a Zex power racer series plug. I ran alot of ngk's, and, went to the Zex plug. They will not fowl easy. Working good for me. Check them out zex.com. B.
