If you don't get Honda's own, these work very well: go to PartsNmore.com and look up this number under the CB750F listing: #17-6823
They are a dead match parameter for the OEM coils, electrically speaking. You will find the wire connectors to be "backward", but even if you just plug them in so the genders match, they will work fine. Be sure to get new sparkplug caps, too, in the 5000 (5k) ohm type. The ones for the "F are #VD05F and #SD05F.
I've used these parts on several of our bikes, and they work perfectly!
