Schematically, they're no different from the '96+ coils as far as the OEM wiring is concerned. I see no reason why they wouldn't work, albeit the dwell profile might want to be re-examined, as the core & windings appear physically more compact.

I'm glad we have people like you on the forum with a remarkable technical comprehension so dumbasses like myself can have nice things and still be certifiably retarded.

???
I can understand a little when folks go gaga over the complicated stuff, but this is easy ****. You look at the FSM wiring diagram for 03-05, and each coil has a +12 feed from the "engine" fuse, a ground wire, and a trigger line from the ECU that's +5 active-high. Exactly the same as all the other Miatas from '95.5 onward when they eliminated the tach wire and moved it to the ECU. The newer coils are packaged differently, but from from looking at the wiring diagram you'd never know they weren't the same part.

evan, your ****'s an MSM isn't it?
item 1: the favorite toyot cops dont fit into the VVT valve cover. one has to change.
item 2: the MSM has a different valve cover. measure the spark plug holes. the COPs are .956 give or take. I'd want a full .040 larger than that just in case. call it 1 inch. if they're a little smaller it's probably fine.

Hold the phone ... I'm confused already. If 95.5 - 2005 are the same wiring for COPS, then why does Savington (here: https://www.miataturbo.net/forum/t20437/) offer different versions from various post-95 cars?

Can you post a more specific link (like, to a particular message)? I skimmed through the thread but didn't see any wiring diagrams. They did change the connector in '03. From '96-'02, they used the same 4 position connector as '94-'95 but with only three wires in it. The '03+ coils went to a smaller three position connector. There is no apparent difference however in the signal levels, the wiring, etc. IOW- they're mechanically different, but electrically identical.
I'm sure there are some fitment differences in the bracket to hold the COP as well. '99-'00 had the cam sensor at the front of the head, '01+ moved it to the back. Plus there was the switch from the rear-mount coils to the CNPs, which would have required another mechanical change to the valve cover.

****. I have my Toyota COPs sitting right here, I never knew that they don't fit. What part of the pencil doesn't fit? Is the girth of the pencil bigger than the hole's diameter? (I tried really hard to write this down without this being another quote on someone else's sig, but alas, I failed miserably).
