I have been using K&N filters for years with any problems at all and if properly cleaned and oiled you will have no problem at all. Our present truck has had one from new and after 105K still on the original MAS and the inlet tub is spotless. My last work truck before I retired had one for it 100K in some very dirty conditions with the same results.
