So with the pack saying 0.45 would that be for a duel build, if so then I'm fine but I always thought they only advertised what it would be for single build plus they are 3mm idAnyways, assuming 3mm ID, they check out as kanthal, around 0.8 ohms each coil, so half for a pair, the reading you are seeing is about right, ie around 0.4
