    I assume you mean the throttle body...


    And if so, yes. But you need an adaptor plate. Isn't really worth it in my opinion until you get the larger inlet on the larger intake.

    No idea.

    Don't go with the FAST throttle body though. They have issues with sticking.
    Honestly, I would put that money towards something else. Little gains to be had since the intake will bottleneck that big throttle body anyways.

    Well...

    The FAST intake is a good one. But as you mentioned...pricey.
    Wow...I kinda feel lacking on throttle body's...
    Been a while since I looked. Last I checked, people were getting Nick Williams TB's.


    What other mods on the car? More than likely, the LS6 intake with a ported/polished stock TB is plenty.

    I'd look into a set of heads, or get your heads ported n polished
