Your engine uses "Coil On Plug" style ignition system. And Unfortunately, you specific model is prone to have coil failure.
But before you change that plug, first confirm the fuel injector for the num:5 cylinder is firing to eliminate that as a cause.
I'm pretty sure your issue is with the coil. So if the injector checks out, change the coil. It's very simple procedure.
