Don't want to argue if they are good or bad. However, if anyone is interested I finally crossreferenced the K&N part number and have been running it for a couple days. The K&N number is 4961 (E-4961 to be exact). It is a sythetic "industrial" filter that doesn't require it to be oiled, just cleaned. I bought two of them and plan on giving them a try. After I researched them on the K&N site and did a bunch of cross referencing, I ordered them on Amazon for about $38 bucks per filter.
