I remain skeptical. I suspect some of those physics types could do a proof
concerning equalization of potential across an airgap, but that's not my
bag.

I have tried +4s on my 84. Didn't run worth a damn. Guy down at the shop
doing my smog said the plugs were too hot for the 1.9. I don't believe him
either. The point is, the three prong Supers do a fine job, and last just
about forever in the wbx1.9. And are less than half the price of the +4s.

Anyone want a set of barely used 4477s? I'll trade them for that 85 with
100K on it. ;)
