No intake can give you better fuel economy. If a simple intake would raise the fuel economy they would have done it at the factory as they have federal mandates to meet for their fleets. It won't give you better hp either. It is just for sound.

Duramax, these high fuel prices are here to stay for many years. I doubt we will see oil under 80 a barrel for a decade. I will take the fuel economy any day over an engine sound and to feel manly.
