hi wallacej -
the seal forms a tight fit between the airfilter to the under seat ducting. By removing the seal - more air is allowed to enter the air filter, in other words to bypass the seat duct. Removing the seal does NOT allow air to bypass the air filter in any way.
The SAI is explained in this tread started by corner banger.https://www.triumphrat.net/cruisers-t...radicated.html
I am not the expert - but I am 99% sure my performance gain was by removing the seal. The SAI removal helps with excessive burbling and popping on decel.
