How do you clean your slant six plugs, or do you even clean them at all?

The real issue with those was people would not blow the media out of the plug when finished. JC Whitney used to sell those as I recall.

Yep, ours was probably jc Whitney. As often as those stand up jet skis fouled plugs, we would have gone broke buying new plugs.
