Air Plains O-470 Airbox Unairworthy. I just removed my old airbox and installed the new Air Plains airbox. Cessna 180G O-470R I know how frustrating it can be to find some of these so let me know if anyone needs one as a starting point. THIS ONE IS NOT AIRWORTHY. You will need to purchase the bushing and shaft kit and install. Holler if you want more information!
