TONY'S D40 st

Im just about to buy a K&N air filter for my 2011 Navara D40 but I'm a little hesitant about it as I've heard a few negative things about the K&N filters on the D40. Apparently there's some issue with the filters clogging up the air flow meter, is this true? Can anyone clarify this for me please... What is everyone's opinion on K&N vs Stock air filter??
