Speedmaster Downdraft EFI Final Installation Video plus Factory Five Cobra Updates
This is my final installation video regarding the Speedmaster downdraft EFI individual throttle body intake. This one summarizes my overall thoughts on the Speedmaster intake, for which I give it a 3.5 star rating, but I would buy it again. Also a few other updates on the Cobra, including fuel lines and plans for what I'm working on next.
