Just saw these are on clearance for $99. Seems like a good deal and perhaps cheaper than new OEM filters to boot. I just bought 2 so there were still some left for 456’s, others seem to have sold out. Figured I would bump it in here. https://www.ferrarichat.com/forum/threads/bmc-air-filter-clearance.619117/
Be very careful how much oil you put on those filters or your MAF sensors will take it in the shorts.
I tried the BCM filters, and after about 8-10 months the heat in the engine bay turned the red rubber/plastic material of the BCM's to jello. They literally fell apart when I took them out.
Another reason the engine bay should have better air circulation. I am seriously thinking about adding some louver vents to the hood. I have K&N filters and they have been good. Never any problems.
