Man a Fre TBI kit has the amazing price of 2500 $!!! This is not for me...

Downey one seems to be some better:
Downey Off-Road Fuel Injection
I just can't understand if in Poer Breather TB is all included or I have to add coil, module, plugs and all that stuff (althought it would be only a few dollars more expansive).
What do you think about that kit???
