what is a diffuser

 

3Dog, a diffuser is a device that is, if I am correct, mounted either in the front of the car, on the side of the car, in the rear of the care. When mounted underneath either the front or the rear, the diffuser corrects tha airflow and smooths it out so that the vehicle is suppossed to travel faster, something to the effect of lowering the coefficient of friction. I am no rocket scientist but that is what I believe a diffuser is. Also, it looks cool. THe diffuser on the GS in the pictures is the black panel located between the two mufflers with the fins coming off of it.

 

thanks i saw that in the pictures but had no idea what it was
