Is that a dry, or oiled filter??
I now that the EU FiSTs are MAF based, thats because the Injen Intake and others from the States does not work on our Cars.
I clean the MAF sensor every Time i change or cleaning the Filter, never had any issues with oiled Filters since i have the Car for 2 1/2 Years and 76000km

And yes it is oiled, to the Question if the MAF Sensor gets damaged or something else, the answer from BMC is:
No, it doesn't.
However, try not to put much more oil of what is indicated in the instructions of the filter regeneration procedure. With the right amount of oil, the air sensor will be fine.
Still enjoying following your build, Doc!
Have a question though (just went through your whole thread again to see when it happened):
Why did you switch from the GGR intake with the white induction tube to the Mountune with the stock induction tube and the BMC filter?
Secondly, have you considered the Velossa Tech Big Mouth? Just seems like a sensible addition for either setup (especially the GGR to get more cold air into that setup).
Thanks TrickSTer!
I changed to the Mountune Induction because the GGR was to loud for me.
The Guy that have buyed the Induction wanted the Hose too so i selled it together.
I want to buy a Induction Hose again, but in Red or Black, the White one was getting dirty really fast...
If want a Open Induction back, i will buy the GGR again, it was very good.
The Big Mouth is very interristing for me with the Mountune Induction, but i want to make a Custom one myself in the Future
