You'll need some feeler gauges to gap them, if I recall correctly it should be 0.7 to 0.8mm, but please check that before you gap them.
Yeah, it's not a mega hard job swapping them, makes it even easier if you remove the airbox and battery. It also helps if you have tiny hands!

plugs come out the box ,gapped at 0.6,with should be the right gap(done from factory)
unless it wildly tuned.........and just fitted mine straight out of the box!!!

what heat range will you go for 6,7,8's
and they are bkr?eix
6 and 7's are fine but 8's are best for highly tuned cars
i've been running 7's in mine for ages and no probloms.
but sure people will disagree..!!!!!!!!!!

Where do you chaps geneally buy your plugs? Do any of you use Denso Iridiums?

Considering adding some fast selling Subaru items to my eBay shop thats all.

i run bkr7eix(iridiums) but am over the 310bhp
pfr6 or 7b's are fine...for 220-270bhp
the number is the cold rating!!
any i listed will fit straight in your car,straight swap....
if you want some pfr7b's i can find you some,cheaper than £5 a plug
like most places...
just sold my last set!!!!but can get more...give me a p'm
