Hello. We bought the car with these parts already on it, the previous owner had them installed. Does this part affect wind noise, positively or negatively? Actually I want to remove it, but it's good in rainy winter weather etc. since my dad smokes. I'm torn. Does this part increase wind noise???
Translated from Turkish
Mate, it varies from car to car, but it might make a whistling sound occasionally, but if you want to ventilate the inside in rainy weather without using the AC, it works quite well. If you're not too fussy about noise, just leave it as is. If it makes noise constantly, it could be worn out - since these are very simple parts, anything's possible.
Translated from Turkish·Sök gitsin.
The sound thing varies between different cars and designs, but it generally does happen.
Translated from Turkish·If it's suited to the car and properly installed, it won't make any noise at all. But if it's bad, it whistles at speeds of 100 and above.
