Agreed with everyone else get rid of the crappy "cleanable" filters, there is more than enough scientific proof and studies to prove all they do is gum up your sensors, screw your mileage and let far more dirt in your engine than a good paper pleated filter. I'm not a diesel guy but once you get rid of the K&N clean any sensors you may have in the intake and clean em well, might want to clean the throttle body as well afterwords no doubt you'll find them both all gummed up with ****.
