I was so sure that the quick lube guys overtightened the plug or something. But, it just might be that the ECS drain plug was no good. One of the employees had to drive me home to retrieve the OE one.

The magnetic ECS plug might have issues because the magnet appears to run all the way through the plug, but then falls just short at the very end of the head. This leaves only a small hollow chamber at the most vulnerable area of the plug.

Either Way, I do not know why I go to the quick lube places, they charge the same as the dealer, and I brace myself every time I go in for an oil change.

A quick google turned up some other forums mentioning bad aftermarket magnetic plugs too.
