Listen to jeff, I am running BUR7EQ in the leading and BUR9EQ in the trail. I have a 2nd gen direct fire conversion.

BR9EQ-14 may be a little cold. Here is some trivia for you. Which plugs did the HC Luce use? BR7EQ-14! That's a hot plug. It was for an automatic tranny luxury car. The sedentary driving style requires a hotter plug to keep deposits from building up. You can probably use BR9EQ-14 in your engine and have no problems, but just remember to open the secondaries from time to time and drive it hard now and then. You know, typical RX-7 style driving.

oh there will be no problem in that area.

They ought to stay clean then. Be careful wth cold starts and try to avoid flooding etc.

Mine are wired open and I dove it like I stole it........untill it went pop. Looking forward to the possibilities of another motor now.

Shane.Trammell

In Germany we get BR8ET from NGK for the 1Gen Models. I Think for you in States you need BR9ET, because you cannot go so fast

Shane.Trammell

we can get the 8s but they are special order at most places

BR8ET only has three grounds. BR8EQ-14 has four.
