Ok I want to know if I got the worst luck or if its common to buy traxxas glow plugs and have 3 out of 4 not work before there even used??

Im just hoping its a fluke and will never happen again, 15-20 bucks down the drain.

I did get them to work by tapping them but I refuse to use them, Im not putting anything I got to tap to work in my maxx..

Also what a good plug for the 3.3 thats not made by traxxas.
