After reading this and talking to 2 experts i know ( haha!) Ive decided for my current setup the BR7ef @ .028-.030'' will work great for me and give a better margin of safety with no effect on power.
Also ordered them from NAPA, The stupid woman at Advance auto couldnt find them and said running this plug would kill my gas mileage Stupid *itch get back in the kitchen !!!!!
