Whose using 9.5's and what have you found using them???? I considering going a tad colder (I'm running the 9's all around).

Anyone have a model number for the 9.5's either?
I know for NGK, BUR9EQP is for the 9's but I've had little luck searching for the 9.5.s.

I don't have a part # but the trouble you will have getting them is not worth it... use the 9's unless you are really picky. you probably won't see much of a difference except for in your pocket book.

 

How about 10's??? A lot of people on this board with similar mods use 9.5's to 10.5's so I was curious to try and see if I can notice something either on the *** dyno or that chassis one

Trust me, for what I spent so far this past year, the difference between $8 and $24/plug is negligible.

 

my car seems to just plain run better with the 10.5's, idle seems more bumpy.......but overall seems to run better....streetport makes bumpy idle anyways, these plugs just seem to make it more bumpy than normal...bumpity bumpity bumpity bumpity.....

 

boosted,

what are your mods?
