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.
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.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 Maser was bloody fast once it got going Kwaker was no slouch either.Sounds like someone had gone a bit too mad with the exhaust porting!
iridium or not?
No point wasting your money - since going to unleaded petrol plugs last forever anyway.
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.
