Wiggins Plug 3in. & 2.5in. (-40 & -48)
thingiverse
These plugs are used to cap off open pipes while working on your car. Nothing worse than dropping something into a charge pipe. These are for 3" (-48) and 2.5" (-40) Wiggins connections. They have an o-ring groove but you really do not need it if you are just using it to keep things from falling in. I place these in the connectors from and to my intercooler.
