you raise an interesting point about the leaking coils creating a voltage arc that shorts out sensors.
I can have the tubes ceramic coated. but that’s an additional manufacturing process. Then the next issue is how much current are we trying to shield from. 1V or 20,0000 V odds are if you have a cracked coil thats pumping out about 20000 v nothing is going to stop that arc it doesnt matter if the tubes are plastic or metal.
I think the best cure in this case is prevention by replacing your coil packs routinely.
Ceramic coating would unlock a big advantage though.
i'd be able to make the tubes from steel which would lower cost and has way better thermal properties than aluminium.
I finally saved up the money to do this so i there is still interest pm me or text me at 9407357295.
and I will have them made. I wont take any orders until I have the parts in hand. I just dont want to invest in parts no one wants
