I have a granatellin Mass Air flow sensor near new in the box. I had it on my 2000 SS for about a hundred miles since i have only had the car for about three months (was not a daily driver), and now I having to return it to stock. I will sell it for 180$ shipped. This part is worth it. It added an extra 9 HP at the wheels at our local dyno day. Offers welcome

 

9 hp?
ummmmm no.
