        5 2013 GT - Mamba Installation Time: Afternoon

        Simple and Necessary.

        Perfect fit and finish. Simple but important part! Did you know however, that this part reduces the size of the intake from the Ford Performance Throttle Body from 90mm to 85mm to fit the 85mm inlet of the BOSS 302 Intake Manifold? Did you also know that there is anouther intake manifold that is 90mm in size for a perfect fit from 90 to 90? The BOSS intake is legendary for sure but why would we ever reduce size in air intake when we dont have too? I will most certainly be purchasing the larger intake manifold in the future. Its the principle!

        Must have.

        This spacer is required if you are installing a boss 302 intake along with the Ford racing throttle body. Look good along slide the throttle body.

      5 Top Rated Questions

      whats the purpose Why is this adapter needed? Is the throttle body bigger then the opening? If so can't the intake be ported a bit so this isn't needed?

      • The Ford Racing 90mm throttle body is physically larger and does not have the same recesses on the back side (mating surface) to bolt up to the Boss 302 manifold. It will not sit flush against the intake manifold. This spacer provides the clearance needed to bolt up the throttle body to the intake manifold. Do not be fooled into thinking you can get by without is a must have.

      Will this spacer fit on the Holley sniper manifold along with the Ford racing 90mm throttle body

      Could it work on a 85mm bbk throttle body???

      Hello Would you need this part to make a 90mm BBK throttle body work with a boss intake or no?

      • Hello. This Ford Racing part would not be required to match up a BBK 90 mm throttle body to a GT model Mustang with a Boss 302 intake installed. A Ford Racing 90mm throttle body would require this part.

      Could I use this adapter to be able to use the ford racing 90mm throttle body on a 2016 mustang gt?

      • This particular adapter will only allow you to use the Ford Racing 90mm Throttle Body on the Boss 302 Manifold. For the stock intake manifold you will want this adapter kit:
