The TSR plate retains the filter when the silencing tube/snorkle is removed for less restrictive flow.
On blower applications, flow to the blower is affected by the following, based upon the maximum CFM:
1. Tube diameter
2. Number of turns
Whereas a velocity stack is intended to improve flow by accelerating the air flow from a larger diameter "funnel", the TSR plate simply has minimal restriction for flow to the filter.
Although there is a science for intake manifold design, whether from a single carb/throttle body, or dual quads, or tri-power to a single cylinder or a V8, a silencer tube does just that-it decreases noise level. The "bowl" on the CB1100 silencing tube/snorkel appears to allow incoming airflow to turn 90 degrees with less restriction.
When the term snorkel is used, such as on a New Triumph Bonneville, it is designed to draw air with a minimum amount of water content, when riding in the rain.
My 1967 CB160 could have used a snorkel. Whenever I road in heavy rain, the filter element under the side cover would saturate and the motor would die.
The mod on my CB1100 would not be the best for riding in heavy rain.
