My logical explanation was to cut it with a rotary tool... it probably has something to do with emissions or something but it is required to replace it with superchargers or you lose psi. It's usually replaced with a felt circular gasket from TRD, you can cut it, replace it or leave it
Maybe
Hi Viper,
I do not know why, but I do have two ideas.
The first guess: That slight protrusion from the shim disrupts airflow to make it more turbulent, maybe helping the air mix better down the tubes later on. Mixed, or turbulent air lends to better burning. One common example of it would be lighting a match and cupping it with one hand to stop the flame from being put out by wind.
The second guess (and much more likely): It could be a restrictor plate--limits the horsepower of an engine. Think of a restrictor plate used in Nascar at select speedways to limit horsepower, speed, and maybe acceleration. It could be there to comply with someone's pollution standards or help disrupt engine noise, but it would seem to be detrimental to engine performance. I'm gonna check to see if I have the same thing sometime this week.

I installed the TRD o ring gasket and didn't notice any gains. Search TRD O gasket mod to do some reading. The gasket was $8 so you won't be out much if you swap it out.
