Is an Aftermarket intake more harm than good?

I’m putting an aftermarket air filter with a “worked” carb on my Lifan 79cc motor.
I ordered an aftermarket intake, which is basically just a bent pipe with a rough inside surface. I plan on porting and polishing it the best I can by hand with sand paper.
But my question is, does an intake actually increase performance? Or would a direct connection from the carb to the head provide a more efficient fuel supply. Thanks!
