I have the Revi intake from Racing Beat installed on my car and would like to know when is it necessary to clean the filter (every ??? KM or miles if you prefer)? Does the K&N Filter Recharger Kit any good for this filter or should I use another one?

Thanks!

 

I think it just depends on how dirty it is. If you dont drive that much its not going to get all dusty. But I live in the desert so I change my filters by the book.
