Anybody running these kind of Air Filters on a tunnelram

Sorry I was more interested in the performance etc of the air filters. Guess I am just balking at the cost of them. Lol I just found some k&N 9 inch diameter 3.5 inch tall filters that would work. They are a lot cheaper. Lol that just seems like a crazey amount of money for a air filter.lol guess I am just being a tightwad. Lol
