All wishful thinking.

And anyone can get their fuel economy readout to show a high number for a short time, means very little to the overall fuel economy of the car.

 

Correct, that pic was highyway only. Before I installed the intake, my average city/highway mpg readout was around 24.5 - 25.5. My average now is around 26.5 - 28. So it seems to have given me about a 2 - 3 mpg average increase since I installed it & driving normally the same way I always have and traveling to all of my usual weekly places.
