Testing spark plug wires with a multimeter (ohms)

Ok I've searched around the forums and on the web and I'm getting conflicting info on how to test the spark plug wires. I know there are other more definitive ways to test the wires but I wanted to just do a quick ohm test.

This is what I did but please educate me:

Set mutimeter to ohm or Ω setting at 20K
Connect the red meter cord to one end of the wire and the black meter cord on the other end
Reading is 1.56 (wire is about 1.5ft)

So I'm assuming this is good since it has low resistance but I'm seeing conflicting articles on the web that say it should be reading between 6-8.

So whats right? or is my wire ok base on this quick check?

Thanks!
