Carburetor Airbox Assembly

Adapter plate is sold separately. The airbox assembly is sold as pictured. 

If you have an Air Plains 172-180HP that was done prior to 2011 it is very likely the original airbox was modified per the STC and reinstalled. Air Plains has improved the upgrade kit to now include a new airbox assembly ready to install right out of the box.
