My PFR 6's are gapped to 0.6mm. Not sure if 7's should be the same.
Easy but fiddly job. Passenger side - remove battery & washer bottle. Drivers side - remove air box etc. A good socket set will be needed with some small hands!!

PFR6B - for no mods... or filter, decat dowmpipe.
PFR7B - for remapped motors with increased boost levels.
The 6 and 7 part of the code is the plug heat range - the lower the number the hotter it runs. That's why 7s are fitted to motors running up to about 450bhp - can also get PFR8B or NGK Racing 8s for really high power - as the 7's colder running helps with heat/pressure management which helps with engine safety/optimal running.

You can get 'em off eBay, individually boxed, for less than £30.Just sell on the 6's on eBay or here, for about £20, so you won't be out of pocket by any great degree.
