    "i" throttle body question

    I have an 88 325 super eta, current mods are "i" intake manifold,173 ecu. my question is would it be a good idea for me to put on the "i" throttle body? I heard I will loose a lot of lowend power and gain minor highend power. leading to me loosing power overall. is this correct? should I put it on or leave it off.

    The intake boot on the AFM end is larger than the throttle body end so it actually tapers off. Go with the i throttle body and boot as it's more consistent and matches the port of the i intake manifold. Use the style of boot that matches your idle valve. It should be the L shaped one ...87-88.
