WARNING: Porsche 928 oil filters

WARNING!!!!

 

Some in M3 SIG say that Porsche 928 oil filters can be used in M3. But, before you do it, read this:

I thought to try it out as well and in my opinion it doesn't work, here's why:

 

THREADS ARE DIFFERENT, see the pictures below:

First, Original M3 OEM filter. Thread is 3/4, about 19mm.

 

Then, Porsche filter has M20x1.5mm threads:

 

So, I would say there is a ig risk that the oil filter might pop out, especially with high rpms. You don't want that to happen...
