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.

Installation Assistance:

View link below to view Air Plains main website for instructions that cover the proper way to install the Air Plains airbox and support bracket on your Air Plains 180HP engine upgrade.

If you have further questions regarding the airbox assembly or the installation please contact us.
