I bought a pipercross one IIRC off ebay. Had it 18months ( since I bought the car) & have cleaned it just once (not that dirty).
No need to buy another paper filter & can clean when I see fit. No probs running wise as some say the oil from a sporty filter can play havoc with a MAF sensor. I dont bother with oiling mine. Really cant see the point & it can oly hinder air flow IMHO.
Performance wise who knows as I have no dpf, a remap & can get very good mpg if I feel like it but I'm sure the filter does it's bit.
