Stick with the air intake and go with a freer flowing (and better sounding IMO) exhaust.

There was a thread not too long ago about similar issues with similar products.
IMO, K&N and similar products are just a scam. Sure, they look pretty inside the engine bay, but they don't do any miracles as they advertise.

About the smell inside the vehicle: Put your OE filter back and see. If the smells disappears, then get rid of the K&N crap.
