Can anyone tell me their experience using K&N air filters? want to try them but am leary of the oil on the filter contaminating the sensors.

No sensors to contaminate. We're speed density, not mass air. I had them in my car prior to installing an Eventuri intake. Didn't really notice any changes.

Still have them, planning on dyno testing them back to back with the Eventuri some time after the temps drop below 105 degrees in my neck of the woods. (I don't want to hear it James. I said no James, no!)

I've had the K&N oiled filters in for a couple months and no issues, I'd love to say they increased performance but if they do it's not noticeable
