Not sure if it is legit. They're using a stock photo.
I've considered buying it and putting it on a shelf just because it is a GM product made for our car that will not be available for ever...I've already got the PAW intake. But it's cool to see that the GMPP is still able to be had new in box.
It makes a guy wonder how much dust they've collected sitting in a warehouse, never seeing daylight. And if you could get the sellers to come down in price.
