Air filter box in accent
 

Hello people

I have a 2005 accent and I was looking for air filter. I wanted to change
stock for a K&N filter when I read about a guy that just took off the black
box that connects to the stock air filter. He wrote that it helped the
performance of the car and the sound, but I wanted to ask you guys how this
affects the car, does it really helps or does it actually damage the car
