Are high performance air filters that use oil on the element worth the money?
In my opinion the original equipment filter, supplied by the OEM manufacturer is usually the best overall choice. Air filters do NOT increase fuel mileage. From that respect, the high performance filters are no better. Other problems include time required to maintain (clean and oil) the high performance models. If oil get on an air flow meter it can quickly be ruined. We remove so called performance filters quite frequently after replacing air flow meters.
