Hey guys,

Does anyone know what size or even better the part # used for the K&N Filter that comes with this process west intake kit
Cold Air Intake Kit - Process West (wrx/sti MY01-07).

I'm on a mission to get one after work but before shops close tonight and wont have time to get in there and check. I have tried emailing PcW but no reply as yet.

Any help greatly appreciated.

Thanks,

Alex
