Hi All,
What spark plugs would you recommend for a GP 150.
Cheers

Never had any trouble with NGK as long as you buy genuine, not fakes from ebay
7 rated for low speed
8 for motorway / high speed / tuned
There's equivalence charts for Champion / NGK / NipponDenso ratings on

As a car mechanic, I prefer NGK for cars. Champion went off the boil, but now seem to be making a comeback. I prefer Champion for the Lambretta. Not fussed at all on Bosch spark plugs, although other Bosch electrics / electronics are spot on.

Both mine are Champion, for some reason a nicer big fat spark, NGK seemed a weaker spark, just my experience, both scoots standard 6v set up
