JP...thanks for the info...very helpful!! Regrettably, once shipping is added, the cost of the filter pretty much doubles and it becomes an asinine price for folded paper. Typically, I buy from local part stores and none, anywhere near me (meaning my state), has a replacement (local Ford dealer would take two days and the filter would cost $35). Anyhow, I saw another post about a K&N so it sounded like other people were having the same issue. Thanks again for the info...good to know...for now I am going to stick with my solution until something better comes along.
