You don't list the correct NGK plugs. That being the case, the poll is useless. B6ES, maybe B5ES if you're running carbs. Bosch W7CC, maybe WR7CC, possibly W8CC with carbs. No extended tips for regular T4 motors, and NO platinum plugs! They work poorly in T4 motors, in fact in most motors unless they're turbos.

Thanks Cap. That's the advise I was looking for.
