What is the right way to install the AEM bypass valve?
The beaded part of the MAS adapter needs to be cut off. This removes about a half inch of material from the adapter. If you purchased your bypass valve while ordering the AEM intake from RRE, this has already been done to your MAS adapter (they cut it for you). The adapter itself can cover up to half of the bypass valve without effecting it’s function. If more of it is covered up, it is not guaranteed to work when needed.
