Should I keep using TR6' if im not spraying?
Im also going to low the shot to 100, so should I keep using those plugs or go back to the stock ones, what you guys think? I swear, this is true. I have done nothing else to my car and I have NOT changed my driving habbits what-so-ever. I've heard of this happening before but some say it doesn't change much...bullshit.
go ahead and change them out for better MPG. NGKs are cheap, gas isn't.
