Which spark plugs. going FI

[astronut1885]

Hey guys. I'm working on piecing the last few parts together for my blower install, and I want to know what spark plugs to get. I am going to run a FRPP blower initially with 6 pounds of boost through what you see in my sig. I know I need different plugs, but I don't know more than that. What should I be buying?
Thanks,
Rob

NGK BR7EF, gap them .032-.035

Thanks dude I basically plan on building the setup at home, taking my Xcal-II up the road to the shop, having them do a very safe tune to get the car there, and then driving the stang to the dyno there and wringing what I can out of it. I eventually am going to jump to 9psi with methanol, exhaust, heads, cams, etc, but for now, I just want more powah!

NGK TR6s are good also

The BR7s are better, I think a step colder also. Sometimes its hard to find BR7s, atleast around here, so the TR6s are a close second.

Why are the br7s better? I have tr6s and they seem pretty good other than the fact that they dont last that long.


Well I just checked, the br7 has the v power electroid while the tr6 has a conventional one. Maybe ill try those next. Or iridum.
