            Spacer Review

            It's a perfect fit on the factory intake. Comes with new hardware and gaskets so not to worry. Looks cool too, I have a Ford Racing blue engine and it sort of add's a cool pop under the hood.

            composite spacer

            The composite heat spacer work exceptionally well better than I had hoped the upper intake manifold stays the same temperature is the outside air with a definite increase in horsepower

            For future purchasers

            The spacer fits great gaskets great OEM quality but the hardware is not correct for a 94 or 95 gt intake. Just take your old stock hardware and pick up half inch longer ones at local hardware store. 5/16-18 thread. Other than that it's exactly what I asked for.

            Life saver

            I searched high and low locally for a solution to my high valve covers. I'm building a 5.0 from the ground up and it took forever to find this thing. The hardware is a little funky but that's something for ford racing to remedy other than grabbing hardware from the local aces this is a great buy!!!

            5 1992 GT - CarCigarGuitar Installation Time: Less than 1 Hour

            FP is da bomb

            I trust anything from Ford Performance! With that said, I put this on my '92 fox 'vert w/ stock intake. First: the item is high quality. I mean it, she's beautiful and the two gaskets are top-notch. Second: Fit was perfect...hole sizes, external trim. Third: Gains...notable improvement at idle and take off. I like the grumble that came with the installation. Fourth: Install was a breeze. The biggest pain was two of the four screws holding the intake plaque striped and i had to easy out them after a trip to Lowes. Fifth: i have my EGR and smog system installed. The BBK spacer does not have the hole for my EGR...wasn't going to tear into a newly purchased item!! This FP one has the hole. Last: No clearance issues. Again, stock intake manifold/stock hood on my 5.0. Not even a mark on the hood's interior liner. In all, I'm very satisfied and recommend to anyone. Now to figure out new timing or tune............

            Great purchase!

            Noticeably different temperatures to the touch on the upper intake. And gives you some more clearence.
