I was just wondering what you people generally run in your 7's and if I should stay away from that bosch 2,3,4 tip stuff. I have an 1986 rx7 n/t

 

Use NGK #7 leading and #9 trailing. I'm not sure which is top and which is bottom.
I'm not sure why, but these are the only plugs we can use on FCs...or at least the only plugs I've ever heard recommended here.

 

u have to use the oem ngk plugs.. they have no external tip/electrode on them.. and btw the top plugs are trailing and the leading are bottom plugs

 

Yeah I installed a set of NGKs on my seven a few months back and it made a difference. My old plugs were toast.

I got mine off eBay too, for a pretty decent prie. (Don't remember what I paid.) Well worth it.

Should I buy "hot" or "cold" NKG plugs. I know one of those types are mainly for cars driven at high speeds or that are heavily modified. All I have is a stage 1 street port. I will be driving at high speeds, I also will be driving stop and go. 1986 rx7 n/t.

 

If its non turbo, you should be fine with the 7/9 combination.

 

just go with a 7/9 combo

 

ok 7/9 it is.
