IMPROVED GAS MILEAGE IN MY 2004 QX56 BY ABOUT 1.5 MPG. ONLY USED IT FOR ONE WEEK.

I installed the spacer in about 30 minutes. Fit will with factory air intake. Noticed better bottom end response and improved gas mileage. Went from 15.5 average to about 17.2. There is no "whistling" sound. Good addition.

Put this on my F150 Ecoboost. Kind of difficult to put on without disconnecting the hose going into the throttle body because it blocks the nuts. Aside from that a pretty simple upgrade especially if you combine it with the AFE intake. I'm loving the combo of this and the Magnum Force intake. Noticeable power increase and fuel economy is better. Seems a little overpriced for no more than it truly does but compared to a lot of performance upgrades, not too bad.
