We made these due to a need in house, and figured we would offer them to you! We have three choices. The 52mm pod allows air past. The 60mm Eboost2 allows some air past but its tight. Finally, The ngauge mount. It is not flush like when you remove the vent, but it still looks good and it allows you to have easier access to the sd card if needed! It is made in the USA and fits between the vent housing and the trim bezel.
