Swirl valve?

If mean someting like a Tornade or some such addtion to the inatke to "create a vortex of air for better air induction" they are without exception scams and will not do you any good.

The extra restriction will likely lower performance (slightly)

pretty sure he's talking about some sort of solenoid that has to do with emissions.

the valve that vents the gas tank back into the throttle body? the solenoid is located on the rear of the upper intake next to the throttle body?

no you will not gain any hp from removing this valve. youll smell gas if you do

Swirl control valve...most Nissan engines built that time had one of these. Helps with low end power.
