They don't seem to be made from that great a material, been there done
that myself.

Be aware there are two routing options around the throttle body heater.
The old type is a round disc mounted on the bottom of the throttle. The
later style (more common) is a plate between the throttle and manifold
plus a U section below the throttle. One or two of the rubber hoses AND
the intake boot are different as a result.
