Would like to add some information.
About heat absorption, in my solution, that places filters in the front of the engine, I can confirm they get hot, but doesn't get hotter than hoses and lines got earlier. Only difference is when you compare by touching them, because rubber hoses have lower "thermal conductivity coefficient" than aluminum, so that they don't seem to be so hot when you touch. And when you touch aluminum, it seems pretty hot. But all of them are staying about 50/122 ºC/ºF or 60/140 ºC/ºF. I don't see a problem there. Sure you can wrap in a reflexive tape, but after a while of engine running, everything will come to a thermal equilibrium and sit at the same 50 ~ 60 ºC.
About pressure drop, in my solution, that uses a 42mm diameter (like NRW and EuroPowerMotorsport products) and 43mm lenght filter (that's half the lenght of NRW's), I faced a 4 psi pressure drop at max load engine redline.
About filter span, can't say, because I didn't run a significant mileage yet. But will soon. I'm willing to monitor that by the pressure drop increasing over time.
I heard people talking that the root cause of injector sticking is the pump strainer getting old and desintegrating. Would prevent that replacing the entire pump. Okay, no problem with that, but there's no certainty on it too. One certainty is, if you have a 10-micron filter, you'll be protected from that.
