jazz,
I rememeber reading a very interesting experiment on the oiled filters vs the dry papers. The final result, of a scientifically controlled experiment showed that the best performance was gained using the stock paper filters in almost every application they tried it in. The guys that did it ran a huge construction company and spend thousands of dollars a week on replacing air filters. The oiled filters, they used K&N nad Uni filters, all failed miserably as they all allowed much larger particles to come through the filters, requiring more frequent replacement and much more friction damage to the motors. They used them in large earth moving equipment, and their fleet of work trucks, big and small. In every case the paper was shown to work better at filtering, the sole purpose of any air filter.
I can't for the life of me find the link but if you do some searching it will show up, it was called something along the lines of "K&N exposed" It was well writen and made sence to me.
With that said, I still have the K&N air filters on Speedy.
