I bought a 2001 f150 that has a cold air intake already on it, but I don not know what kind (brand)of filter it is on it. I was wanting to clean it but do not know how. It is not a K&N it is a dark blue coler almost purple. It does not fill oily like my old K&N did.

 

why not just replace it with a k&n or other high performance filter and start all over. New truck new filter. that would be my best bet...

 

That is what I am going to do. I took it out to day and it has rubbed a small hole in it from rubbing against the fram under it.
