You could replace it with something like this K&N kit.

I really only need a hose that would go from the throttlebody to the existing airbox. I'm not interested in the "cold air" box.

The link I provided above is a replacement inlet pipe that goes between the factory airbox and the throttle body, plus a K&N filter. Using the filter isn’t required, but that’s how they package the kit.
