    I think you should go with the regular plugs especially if you change them every year.

    I'd spend the extra money on something that makes more of a difference.

    I couldn't find your car on Rockauto. It must be quite rare.

    I couldn't find any 1.3 L Protégé or 323.

    Speaking of filters, you should look into replacing you fuel filter.

    On our car it's buried inside the sender unit in the gas tank.
    People didn't realize we had one until it plugged up and burned out the fuel pump, then they had to replace the entire sending unit.

    Here's the big list of things to consider inspecting.
    It's for the P5 but it should apply to you as well.
