It’s not easy to get to as depending on how it is connected the clips need to be cut off. One thing I have done in the past with success is use throttle body cleaner and spray down the tube. It is easier to get it off and clean or replace it properly but if you are stuck to try and fix. The seals for the AOS on my street car are going as such I get oil in those lines and need to clean periodically. Otherwise I do not know of an easy way to get it out of there without intake coming off.
