Standard Type........PFR6B-11............PFR6B-11C

HTH

Pay £800 quid for a service and they cant get the plugs right

Looks like PFR7G are for Scoobies and Integras.

I'd go for some HKS S40i's. They aint cheep as the are irridium, but only need changing every 60k + the are recomended by Nissan when running higher than standard bost.

how much is 'not cheap'?

About £19 and every range you want

how often do stockplugs need changing? and chris how often do your greddy ones need changing?

GReddys are every 60k but i'd do less than half of that mileage IMO

so when people talk about different heat ratings etc what do they actually mean?

 

im on a fairly standard engine at the mo, filter, cat back exhaust, chip, underdrive pulley and boost jets by next week - what should i be looking for?

I'm sure there's more science to it than I apply, but if you check your plugs regularly you can tell from the colour of the plug if the car is running hotter or cooler. Hotter plug helps if the burn colour is a tad richer (cooler) and vice versa I think
