Review on Four Seasons 33415 Filter Drier by Mauricio Woodard
There is a sight glass!
Sight glass included (same as original Nissan dryer). It's just sealed with tape. In the photo I removed the tape. It also comes filled with dry nitrogen. Wait until you are ready to install before removing the caps. It also has two side female thread connections for a low pressure switch.
Pros
- Part number: 33415
Cons
- Crumpled packaging
