K&N filters have proven to filter poorly in the past.....coupled with reports of fouled sensors, etc. I'd never use one, particularly not on a forced induction motor. This was a well known issue on the turbodiesel forum I used to frequent. My advice would be to stick with stock or a least a stock type filter.
