K & N air filter, how many points?

I am looking to class the 2003 996 I recently bought (and had a blast at this past weekend's PDS with my daughter co-driving. Thank you to all the volunteers.)
The only modification on the car is a K & N airfilter and intake a previous owner installed.
I realize this bumps me out of Street Stock class to Stock class.
Is this going to cost me 4 points or what?
