    Comments about K&N Replacement Air Filter:

    You are supposed to change the paper filter @ 15k, at a cost of $35.00 each, so for $52.00 I never have to change it again, i only have to clean it at 50,000 mile from now. I think to is a enviromentally responsible thing for people to do, considering if the car goes 250,000 miles, thats 17 paper filters at of cost of $595.00, so still wondering weather it is worth it?
