I don't think Spoon has one made for the CL7/9 ... What are you trying to achieve to justify a throttle body upgrade? It's quite meaningless in a mildly tuned NA application since it's not gonna show any gains on either acceleration, power or throttle response, quite a different story if you're going forced induction.
Individual throttle bodies when configured/tuned setup correctly will definitely show gains while a larger throttle body a mildly tuned NA car will see virtually no gains.
There is also no improvement on air intake capacity from simply changing to a larger throttle body without significant mods ala - Engine work or forced induction. This is quite a different comparison to measure against mods like ITBs, or air intakes simply because it's part of the air induction/intake system.
