Alright Ive got a stupid questions. Is there 2 different air filters for the GS? I am not sure what is being called the lunchbox, is the su5589? I am planning on getting the K&N and exhaust, do I need to rejet as well?

Actually the lunchbox is RU2970 check here:

And rejetting after just changing to one of these filters is essential especially if you upgrade the exhaust. List your specs and we can guide you along with looking here:
