All, I have just fitted a K&N panel filter to my Vec 1.9CDTi to compliment the recent BSR remap (and the bottom airbox mod done 2 years ago). This is a new filter straight out the box, i.e. oiled by K&N. In your experience, will this clog up the MAF sensor over a period of time with oil or is it only if you clean the filter and over oil are problems likely to arise?

Thanks.

BTW, the car flies along nicely now. Ive never had such a strong acceleration since I owned a V6 petrol engine years ago.
