NGK or Bosch, don't buy fancy expensive ones, just change them an extra time IMO
 
I have Bosch Super 4's in mine which was back when I could still afford such luxury and they are absolutely no different to the standard NGKs I took out as far as performance that I can tell.

When you've spent years mucking around with tuned two strokes - you learn a thing or two about spark plugs - one Champions are often duff out the box! Two, never had a duff NGK - three they don't oil up half as much as anything else! Had a fling with Bosch and they didn't seem to be much better than Champions.

The 2 stroke Kwaker was a real bugger to start when cold as was the maser, had to start on soft plugs to warm up.
 
ive ordered iridium anyway as the price on 8 was only minimal they claim better fuel economy but we will have to see 54 quid for 8 ngk6418 (iridium) against 48 quid for 8 ngk3199

How pray does a spark plug give better fuel economy? Some people will believe anything.
