Nicholas R from , said, "this full system and the scoop really helped out my truck. Definitely opened up my engines breathing and has improved my overall gas mileage by a little over 2 miles a gallon. The throttle respond was greatly improved, idle has smoothed out as well as felled about 200 rpms. Great product even though it's a little expensive it's not when compared to others of comparable quality. Product was installed on a 2008 Silverado 1500 Z71 4X4."
