has anyone done any testing regarding the resistance properties of cheap bullet plugs you can buy from ebay, versus novak, tekin, CC plugs?

I bet the differences are in the .001 to .000001 ohm range. Without having samples of all of them to test on my works milli ohm meter that is the best guess I can come up with. The difference is so small that us "everyday" racers will not see any performance gain.

Yeah I didnt think so too. I'm sure novak and tekin dont make the plugs themselves and just outsource their plugs, and they are probably made by the same company that makes the cheaper ones.
