how does one go about choosing the right spark plug? Yes, I searched - and there is simply too much data to sort through. I am pretty sure the puge ratings has to deal with heat, but I don't get the how/why of choosing the right plug. Are there any websites out there that make this choice easier?

I am pretty sure I want to go with NGK plugs - are there any automotive parts stores that sell these?


my mods:
SMIC, intake, DP, cb, ecu, y-pipe

 

Check this thread that was going on yesterday:

Not sure about Mn. but I get my NGK 9's at Advance Auto Parts. I also think Pep Boys sells them. I've always run NGK's btw.

 

I would run NGK 9's all the way around.

 

For the mods you got listed:

 

cool thanks guys... I thought it would be either 9 or 9.5s but I was not sure

 

9s all the way around for me too. CJ
