Spark Plug Change
Only fitted the originals PFR6B about 2k ago and from reading and that now running more power than standard fitted some PFR7B and what a difference, smoother idle and more aggressive on boost, why would spark plugs make sutch a difference?
Know the 7's are colder plug would like to understand this.
Done the same on pals car and has reported back the same result.

From what I understand...
The colder plugs help prevent pre spark (det) especially at higher boost and power levels when combustion temp tend to get rather high.
Definately made a difference in the higher rev range of mine, (seemed stronger somehow.) It went bang 300 miles later...
