Last year I purchased a K&N FIPK gen2 cold air intake for my '04 F-150. I have been very happy with it, but when I noticed it was time to clean and recharge the filter knowing it would be a minimum of 24-48 hours to dry properly, I decided on a second filter since they come ready to install. My truck is a daily driver, so short of being on vacation to have the time, I felt a second on very handy. Now each time I need to clean my filter I have a fresh one ready to go! Pretty happy with this set up altogether
