I didn't see anywhere on Stilen's site where they offer the filter separately. I want to have a spare so can swap it out for cleaning without have to wait for it to dry.

 

I had the same issue some 3 months ago. I could neither locate the K&N cone filter or get a response from Stillen or anyone else. I purchased a popcharger filter instead. It fits perfectly inplace of the K&N cone filter, which comes with the Stillen Hi-Flow Air Box.

 

Thanks Andy. Does the Venturi ring fit perfectly inside the filter opening?

 

I've been considering the same thing myself but wanted to contact K&N
about one of their Hi-Flow filters. Same size as the one we have now but
has an open filiment on the end instead of the chrome cap.....understand?
Just need to measure the one I'm using so I can ask K&N with some type
of knowledge about the replacement......haha

 

Yes, the ring fits just as it does on the K&N cone filter. Having an extra filter is a much better way to service the filter. I did the same thing when I used the K&N drop-in filter, as well.

 

The popcharger filter has the open end and fits exactly the same as the K&N one does. Good luck to you on your search. I came up short after much searching and e-mailing and simply gave up.

I got my popcharger replacement filter at EverythingG35.

 

Great. Thanks for the info Andy.

 

in a lot of peoples minds, the stillen airbox is best matched up with the p/c filter, anyway.
