....i forgot to add that if I was doing these mods like these aftermarket plugs and filter, I would be doing so to improve the performance (how smooth the bike is running) as opposed to getting better fuel consumption. I might add balancing the carbs to the list too. But it would be all in the name of getting the bike running smoother. If I get a fuel gain then that would be an added bonus. But it wouldn't pay to just do it as a means of getting added fuel consumption if the bike is already running relatively smooth as it is. If your bike is running smooth and you are satisfied with the power its pulling, then leave well alone IMO. It sounds that you are getting reasonable and near normal fuel consumption for a Fazer. If you need better, you need a different bike with a smaller engine.
