How will new air filter (pods or lunchbox) affect my bike?

[halffttime]

I hate the bulky airbox that come stock with the bike. I want to change it to either pod filters or lunchbox. I plan on keeping the stock exhaust with it. How will this affect the bike? Will I have to rejet?

Thanks guys.

Yep, you'll need to rejet. Have a look here:

And K&N with stock pipe hasn't been easy to rejet either.
The other set up's I ran with O2 sensor in the pipe and got em spot on, that setup I never did.
Cool.
