Carl from all reports I've heard the Polaris bellmouth is a DOUBLE bellmouth;half is cut away to fit on the bonnie's airbox.Perhaps some kind user could sell you the other half for cheap.Apparently the cruisers can use the bell on top AND bottom,while the side mount Bonnie airbox cannot use a right side bellmouth due to the airbox shape.
That's the impression I've gotten, too. Have you tried it? Or have you removed your airbox?

yeah it is a double bellmouth, but i don't think the center portion is wide enough to turn it into two separate bellmouths. i cut off just the curved part of one side and didn't leave enough material on it to attach it to anything

Still cheap at 12$....I of course paid nearly 10 times that.

okay-
what is this snorkel thing? something to do with the AI? if the dealer removed my AI, do i still have a snorkel? and if i do, why remove it?

The idea is that the snorkel restricts the airflow to the air filter. Some say by removing it you get an increase in performance. I must admit I did not notice the difference with my one when removed. You will find it attached to the air box sort of a rubber tube thing and it just clips out. This will be the intake of your air box.

The snorkel is located under the left sidecover. It is a rubber thing that resembles an elephant trunk. Its purpose is to reduce intake noise for EPA noise certification. You can simply pull it out of the airbox. I have pulled them from both of our T100's.

like intake noise!! and i certainly understand the effect of velocity stacks on open race type carb throats, but i fail to see what effect a bellmouth used on this side of the airfilter can achieve . installing free flow filters like uni and k&n, and then having some kind of bellmouth between the carb and filter element could be advantageous. but the filyer should negate any effect of the bellmouth as used here. agreed it makes a cleaner looking set up, but its hardly in view under the panels and seat.
now i am still relatively new to hinkleys, and appologize for asking questions and still missing the point but it seems pulling the snorkel gets rid of somwthing ya really don't need , or in my case, want. as to, if the bellmouth can improve
intake sound, cool. maybe 12 bucks is worth that. i don't see it possibly increasing performance though.

Some say the Belmouth forces more into the airbox. I have not seen any dyno runs without and with the belmouth for comparison.

The only way to know is try it for yourself, and to NOT do it as the same time as other mods. Pulling the snorkel for may, especially SM owners often yields a very considerable boost in power. For me it was probably the biggest power boost of any other single thing i've done, even more than the thunderbike pipes themselves ! So if you pull the snorkel to put a bellmouth on and feel a big boost, consider the fact that it's probably more likely the removal of the snorkel that is responsible for most or all of it. So pull the snorkel and ride for a while, then install the bellmouth.
