After some extensive internet searching I can only find one option that improves intake. A K&N air filter. I cannot find anyone who manufactures a cold air intake for the 2012/2013 535i n55 f10.

Anyone else have any luck?

I read a prior post where a BMW owner said the dealership discouraged the use of a K&N air filter, as the filter oil gets sucked out of the filter and into the intake manifold tripping a sensor causing the CEL light to come on.

Does anyone have any advice, recommendations, comments or experience in this regard?
Take anything a BMW dealership tells you about non OEM parts with a grain of salt. People have been using the K&N drop ins on N54's and N55's for a couple years now and there hasn't been any issues causing CEL's from them.
