I can't help you out with personal experiences with the three prong plugs,
but I do know they a widely used in VWs and Audis. I use Bosch platinum
only, I know there are some Vanagon owners that'll say other wise. But the
vehicle I put them in have better overall performance. This test was done
after only changing the plugs. IMHO
