Those numbers are nominal. When you measure them, there are many factors that alter the resistance. Temperature is one of them. Coils will measure higher as they heat up.
Here's a bunch of details on common coils used in KZ's.

Somebody does make a really low-cost, factory replacement, that is supposed to be 2.4 ohms. No name, but they look similar to the Tec coils the factory used.
I think this is the seller. My buddy installed these last summer and so far they have worked great.
The only difference was they use 8mm wires instead of the factory 7mm wires.
