BMC or K&N Air Filters

[Heavyweight]

I have a 2014 Patrol, looking at upgrade/improvement mods, has anyone used either of these, particularly interested in BMC...I have experience with K&N on motorcycles but not with Diesels

[MEGOMONSTER]

I use K&N filters on my Trol.
I have two, using one as the other I clean and recoil ready to swap out again.
