[Unit 5302]

For the money you'd save on not going with the FR500 intake, and no throttle body, you could nearly pick up a supercharger. The variable geometry intake manifold design was discontinued for the 99+ Cobra's after a tumble port head revision was performed. The 1996-1998 Cobra's came with IMRC (intake manifold runner controllers) that changed the length of the intake runners switching from the long runners to the short runners at about 5500rpm. This was done so the engine would produce more torque. They restricted performance somewhat, and when removed top end power improved while bottom end suffered greatly.

Don't expect your engine to pick up a ton of power with switching to the variable runner FR500 intake, especially considering how much power forced induction adds on those cars.
