    Regarding coils, below is what I found since pasting the linked spark plug info might be a little more overwhelming. Interesting however, the Toyota Parts Deal page notes that the Genuine Toyota 90919-01265 Denso FK16R-A8 only for the Prius C. Where-as the Gen 2 Prius is noted Genuine Toyota 90919-01240 Denso, of course I think is, SK16R11 with a few vehicles noted used in:

    Back to coils, appears both Prius C and Gen 2 use the Denso 673-1306 or am I making a mistake?

    Toyota Parts deals notes for the ignition coils for the gen 1 & 2's that the part # 90919-02240 can be used in (same Denso 673-1306 noted here?):

    Any thoughts regarding using the Prius C plugs and or the coils in a gen2?

    The more I think about this, the pressure from the latest storm might be getting to my head or whatever it is going around.

    Gets me wondering about those pink genuine C fuel injectors utility next.

    Both engines are one NZ I would imagine if the coils will bolt down to your cylinder head or valve cover rather and are the same length extension wise by setting them next to each other you're probably in good shape I would think by now that the plug would have changed that plugs to the coil so make sure that that's the same I noticed in some of the newer cars the coils are the same but the plug is different so unless you clip the plugs from a Prius C there may be an issue there I can't see them from here I don't have a c here I know it's one NZ but later model one nz's may have different plugs on the coils on the fuel injectors and so forth I would have to physically go out and look if not they probably will work fine the pink injectors one of my older 85 Toyotas had pink injectors so I'm not sure what the color means necessarily again the plug would be the issue and if there's any difference in computer or resistance and that sort of thing you'd want to note that between the two systems it could make a difference fuel injectors aren't that expensive to start sourcing other engines and products for your engine you don't have all the other stuff that the more modern one NZ may have not saying they won't work they're both 1.6 l and all that so fuel and trims should be similar but if impedance changes or something like that then that could throw everything off the plugs sitting them side by side should be the same reach and extension and the heat range should be the same which is the 16 I don't know what the f and all that business is about I know about older Denso plugs but not the newer stuff. Again the plugs aren't expensive enough to make me go search for other plugs used to be between the fine wire Zu plugs and the PQ Platinum plugs and so on for some benefits and differences but these things today probably not so much unless I could get these parts at some kind of huge discount of for free I don't know why I would be changing from my regular dedicated one NZ parts for the model I have and I have plenty so I don't know when I'll be trying late model or later model parts on my old Gen 2 I might never get there
