Drain plug: max length?

[alm001]

My local part store has a m18x1.5 drain plug with a magnet on it, but it looks a lot longer than the ones online for our application.

Does anyone know the max length that can be used?
This thing is a solid 1.5" to the shoulder of the head.

I have one of these - it's made for the car so no need to worry about fitment. 1 1/2" sounds a bit too long to me.

I ended up not running it. Just to be safe. There probably is room in there, but the quality wasn't very good, and the magnet was pretty week.

I will order the right one for the next oil change.

Just a note about the ECS magnetic plug. I had one and found that the metal was very easily stripped by the allen socket. Maybe mine was torqued too much by the last tech, but when I did my own oil change this time, I had one hell of a time removing the plug. Ended up cutting a slot in the plug, pushing a chisel bit up with a jack, and freeing it with a vice-grip!

That looks nice
Much bigger magnet than the LN.

My guess would be that the shop didn't follow the torque specs if it was that tight.
