Anybody know about a secondary mesh filter inside of the air cleaner on a 454? Mine has one and it looks pretty blocked. I'm thinking of taking it out, however it is attached with some sort of glue or goop.

I removed one, the butt dyno said there was an improvement when the throttle was mashed. You basically have to destroy it to remove it from the filter housing.
