Ok , I know search. I did that and I thought I knew the answer, but here goes. ...
I thought im supposed to use Spark Plug-BKR6E if im broke, and Spark Plug-PFR6B-11 if I can afford it.
I went to my dealership and tried to get the bkr6e's and they told me that its the 5e's that are reccomended for the engine.
So why are we recommending a warmer plug, I thought usually go one colder
anyway for now just intake headers n a catback looking at cams- so i should i go dealer recommended i.e. 5s , or forum recommended i.e. 6s ???
