Thanks for correcting that mis-observation. Looks/looked like some minor potting to me too. These have been my go to in Napa Gold form, 7356. Using one now that has been in my stash for awhile and has dome bypass.
When Wix changed the baseplate from the 51356 design to the topic 57356 for Honda, they started with nitrile adbv and dome bypass. Pretty quickly went to silicone adbv and dome bypass, what I'm currently using. And the latest is the topic form, silicone adbv and Wix traditional thread end bypass. So far in my experience, M&H hasn't screwed them up. Knock wood.
Thanks for c&p.
