I agree. Intake technology has advanced from the backyard shadetree to being a fully engineered component of a systemThe stock air filter seems pretty huge. don't know if changing the air filter will be much improvement on this bike. I would definitely not want to eliminate the air box for a pod as is popular on the higher revving Ninja. Honda did a great job incorporating a nice tuned runner leading up to the throttle housing that gives us our midrange torque bump at 5800.
