Do any of you run all 9's for spark plugs? any reccomendations....?

 

I have all the bolt on mods for the stock twins and I run 9's all around with no probs. If you're close to stock, I'd stick with 7s and 9s.

 

ditto with what rx7rage said

 

I put in all 9's in January. Car is basically stock. It seems a little crisper but honestly I'm not sure it made a tremendous amount of difference.

I run 10.5 all around. Does that count?

 

I run 9's platnum in the leading, and 9's non-plat in the trailers. This is the first time though i have tried just using 2 platnum plugs and non-plat for the less used trailers. My car was tuned and drove for 7k miles with 7's, and 9's and it ran fine had no problems at all.

 

I tried running 10.5's but they fouled in an hour, I stick with 7's and 9's.

I have similar mods as importrx7

 

Just changed to all four 9s. The exhaust is already opened significantly, and I have hopes of upgraded IC and CAI in the near future with stock boost levels. But irregardless, I plan on pulling them in a month or so and see what they look like.

 

I was fouling the 7-9 stock combo with my new mods, but not that I have 9-9 its great.

 

i run all 9's i m ok with it

edit mod in sig

 

Cool great input guys thanks!! I blew an apex seal finally, and I put a new (97-98 Rew) in this coming weekend, and I'm just looking for tips and tricks to get er' to run well. Appreciate it!
