FYI... the NGK plug that comes in the 1200 8V is a PMR8B (6378), and NGK USA states that it crosses with the NGK CR8EIX (4218) Iridium, which is more readily available and almost ~50% less.
From Steve below: The factory is now installing a NGK CR8EKB in the Griso 8V SE models, not the Iridium but a standard plug.
