Ok so its time to change my plugs out and was wondering what would be the best for my aplication...now i know that iridium last a long time and was looking on lethals site and saw a set of NGK TR7IX and was leaning towards that. My mods are 2.76 steggy stage 5+ ported welded and portedplenum and tb. JLT, and a custom tune. I dont think i want to have to deal with copper..more looking at platinum or iridium. 18 degrees of timing on91 oct. (sorry so cal) and im gapped at 32 right now. LEt me know what you guys have had success with thanks!
