NGK BR7EF or BR8EF
My 98 LS1 Camaro "I was told" was tuned for a 175 shot. When I bought it it had motor plugs in it I will probably only spray a 150... "But knowing me I will probably go bigger at least the 175" Lol which plugs should I run? How will they act on motor and what should I gap at? Thanks

Our car runs fine on a #10 plug. Sbe, 10:1 compression. Like said, a good tuner can get it to idle cruise fine on a colder plug. Our runs fine on a motor pass up to a Br8 ,but, anything colder will break up some above 6000 rpm. It will idle and cruise fine though on a 9 or 10. Sounds like a 7 is what you need for that jet though.
