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 one parakeet the minimum size cage you should get is 20 inches long, 18 inches deep and 18 inches wide. A pair of parakeets need a cage 30 inches long, and the same deptth and height, while a cage for six parakeets should measure at least 40 inches long, 18 inches deep and 32 inches high.
