I have seen a few on here say the inside of their bladerunner was dirty. I received my today and it looks like **** on the inside. Extremely rough with a lot of extra casting chunks. So much for smooth air flow. I don't know if I should ship it back or try to sand it. For $200, you would think AFE would take more pride. Does anyone have any input?? Won't say where I bought it because its not their fault!!
