    1-148-011 - Speedmaster Downdraft EFI Stack Intake Manifold Systems is rated 1.7 out of 5 by 3.
    Rated 2 out of 5 by from Not great quality I bought this to fit fit on on 302 Cobra. like the other reviews, I had the same issues and had to make a few mods to make it fit. Mine was also missing an injector spacer which was not forthcoming when I requested.one.

    Rated 2 out of 5 by from Quality Issues The manifold is a cheap copy of Borla/TWM and does look cool, BUT expect to spend additional money and time making it work. Vacuum ports were not drilled through from the runners into the vacuum manifold area. The company wouldn't warranty it. Had to drill the holes myself. Had to replace and counter-sink bolts in the manifold valley area since they hit the block. All but 2 of the throttle blades had poor fitment. The blades not only were not beveled, but thicknesses seemed to vary between them. I was able to get the motor to idle, but fitment is still not where it should be. They won’t sell shorter stacks separate. My kit was missing 1 injector spacer. They wouldn't sell or send me another one. Couldn't find air filters anywhere other than a "dome" screen. Since I had to swap the stacks out anyways, I went with Inglese ones which also sold me snap-in K&N air filters. My motor (363) made about 492 crank @ 6750RPM. Driveability overall is good AFTER, the throttle/idle issue was sorted. My builder thought it would have made 60+ more HP with a single-plane Victor Jr.

    Is there a computer included with this kit, and which one?

    Asked by: Johns363
    No, there is no ECU with this intake manifold. This is the recommend kit https://www.jegs.com/i/FAST/244/30404-KIT/10002/-1
