Well, I've finally ran one whole tank of gas with my new intake and my mileage increased about 1.5-2 miles a gallon. I got 20 mpg, all in town driving with a bit of trying it out now and then. I usually get about 18 in town. I haven't wrapped it yet like Brian suggested, I'm still waiting for something before the wrap happens. I can't wait to get out on the highway and see what kind of increase I'll get.
Has anyone with the Needswing intake noticed an increase in mileage?

This intake was a great add on. I'm very pleased with the performance increase and then again with the mileage increase!!
