do it improved performance??

I would not try it. Are you having problems of any sort?

nope....just surfing the internet and found it.....and read some history on it during WWII...and nowdays its make a come back...common used on Force Induction........except this wan on NA engine

I wouldn't bother doing it. This is what i do not like about it"adds damp air to the engine's intake mixture." Well i know for a fact that my car dislikes damp air(will run crappy on humid mornings). Maybe this system could later on make the engine rust?

Hook up a bottle of Everclear to the intake.
