I note in the site catalog that the long awaited turbo plugs are listed as available. Good!
A question-
Is "Turbo Plug" a standardized size, thread and seat taper? Your new-item link to Mecoa-available plugs shows Fuji and several heat ranges of RJL's (or Mecoa's), as well as a tempting range of head adapters. They all "look" like other Turbo Plugs I've seen from other sources.
Are all Turbo Plugs going to be interchangeable in the same way the traditional 1/4-32 glow plugs have been for so long? (Given a suitable adapter for the taper...)
