Rapidfire #8, Rapidfire #12 or Tr 55? Indexing Plugs? I have been running the Tr 55's for quite some time now. I have noticed recently people have been running the rapidfire #8's and #12's. Could the rapidfires suit my N/a Application just as well as the Tr 55's do?
Also what position do the plugs need to be indexed on our cars? I have heard 10 o'clock on the drivers side and 2 o'clock on the passenger side?
Thanks

Re: Rapidfire #8, Rapidfire #12 or Tr 55? Indexing Plugs? I run RF # 8`s N/A (free Mod stock) and their great ! i know others spraying 150`s and the use the same plug,same gap and they work great for them also.One guy pulled 2 each from each bank after 11 full sprayed pass`s and they looked like he put them in the day before.
I dont know about all that indexing BS
just run`em in and snug`em down then ride !!

Re: Rapidfire #8, Rapidfire #12 or Tr 55? Indexing Plugs? My car didn't respond well to the Rapidfire #8 plugs. The idle was worse than the stock plugs and I lost 2 mpg. I recently switched to NGK TR-5's gapped at .045". The idle is very smooth and I regained my lost gas mileage.
