Not Ranked
I know a 3"x14" filter chokes up my chevy 396 and costs it .200 seconds in the quarter mile. The choke / bog issue, air flowing quickly across the top of an open carb can hurt airflow, the engine will also lean out a little due to the lack of a restriction.

In a fit of 16 year old genius, I looked down through the carb while cranking it to see if fuel was flowing, and it was. Flowing straight up in a vapor cloud, around my head, on fire.
