I wouldn't waste your money on it.
The 4.3L engine already has a rather large intake volume which is what throttle bodies use to shift the torque curve lower in the RPM band. As such, the impact of a spacer on this engine's torque curve is minimal if even measurable.
The 'helix' does make a whistling noise, but that is just a performance placebo. Sounds different therefore it must be performing better! Given the large open plenum intake manifold design used, any rotational effects from the 'helix' design will pretty much fade away in the plenum and not really make any changes to airflow through the lower intake manifold runners and into the cylinders.
