I installed the Jet performance Module in about 40 minutes.Everything was included with the Module for installation (except the tools).I have noticed an in crease of about 400 RPM in my shifts and a .02 decrease in my 0-60 ET's.
This cage size is fine if your budgie is outside of the cage most of the time, but if you have a cage-confined budgie, it's going to be much too small to keep your bird happy and healthy. For two budgies, 39- by 20- by 32-inches is a recommended size.
For two smaller compact cars a better size double carport I would recommend would be 20x21. If you are wanting to make the carport fully enclosed with two garages doors then the 20x21 is the most narrow size of the steel garages that have two garage doors.
