how much horsepower would you gain on an 03 wolverine? and would it be hazerdous to water and other elements in your engine?

 

This is about the second or third topic you have posted on this. If your rid ein mud/water leave it on. If you ride dunes or another enivirment where your not in mud/water you can take it off or buy a kit that eliminates the box. If you do this you will have to rejet your bike for the extra air. If you dont not rejet it you will get even less performance from your machine.
