Also I love his disclaimer on his site:

These products are sold on an �as-is� basis, and no warranties of any kind, whether written or oral are made by Morana Racing, and it's agents, dealers, or employees.

That to me says there is no guarantee of any kind for it to fit or work in the manner in which it is represented. Also zero warranty on the M90 blowers he is selling lol.
