just a quick post,,,what spark plugs are the ebst for a turbo fc,,,i used ngk 7's last time i changed mine,,i once heard to use ngk 9's,,,stronger spark???i never heard anything about ngk 9's since or have yet to see them?? https://www.nopistons.com/forums/pub...1047683561.gif

I never heard of using all 7's... most people use the leading and trailing...two 7's..and two 9's



I find it just easier to run all 9's...I have been for a few years...Runs perfect...and this way you don't have to worry about leading/trailing

can i run all leading mines aint turbo..is it possible

??

i use all 9s, its safer and they will last longer than 7s on the leading.

yeah, doesn't matter if its turbo or n/a...i use all 9's in both of mine

So for an N/A it'll be ok if i use 9's in both? The 'ol lady's due for a tune up soon.

wow, i never knew you could run 9's in all the wholes. Very strange. even on an everyday street driven engine?



What exact benifits do you get from running all 9's as opposed to running 9's and 7's?

yeah what the benefits of all nines.....hotter spark?? Better fuel efficiency. My old lady got new 7's and 9's guess ima have to go buy 2 more 9's lol..Not tech 9's lol. Bureq9 lol sumthing like dat

i have all 9s in the car....i thought 9 was cooler spark ...could be wrong
