Plug Help Needed
Who all on here runs the "R" series race plugs and have you had any problems with them? This is not a strip only car. I drive quite a bit on the street.
Also, is their a resistor type plug that is exactly like the TR6 only 2 steps colder? NGK says no in the V power series. They recommend the "TR8IX" which is an iridium plug and they go for seven plus bucks apiece!!??
Help!! Thanks
