I've used those dinky fram filters for years and never had a problem. That could be from a faulty pcv or egr, incorrect filter, or incorrect installation, how are we to know, it's just a pic.

i dont think its the fram ones... its the aftermarket cone filters

Looks like a combo of oil and dirt....Probably one of those cheapie aftermarket foam filters + blow-by

[EG STyLeZ]

the filter was probably leaking cause it had a hole somewhere

guy prolly overoiled his aftermarket cone far too much...

[Dj_Stylz]

If you are after engine reliability and prolong engine life, paper filters are the way to go. K&N has been notorious for letting dirt through.

If you run an aftermarket reuseable cone type filter, do an oil analysis to see how well your setup is working and then you can revert back to paper if it is letting too much dirt in. This will show up in the Silicon content of the oil.

For some reason, I hear a lot of BMW owners complain about the price of parts, which to me is ridiculous, it's not like they didn't know what they were getting into when they bought a BMW. "But how come an intake for a Honda only costs $80?" I just tell them to go buy the $80 intake an see how it works out. LOL.
