Dude how can that little plastic increase HP and fuel at the same time... Trust me this is BS "Tests have shown up to a 33% increase in MPG. And have also proven 20 HP gains." What tests? and why exactlly 33% it would differ from car too car this item is just a rip off dude!

Read the following article from popular mechanics. The magazine tests a very similar product. In theory it works, but because of all the complex valves in today's modern engines, it does not work. In fact, some tests proved it decreases gas mileage because it restricts air flow.

NO aftermarket product will decrease your fuel consumption. Many agencies have tested these so-called devices, and the results all came up as "you're wasting your money".

Lighten up your right foot, remove unnecessary cargo, check your tire pressures, and then just admit that you're driving a 2 and a half ton SUV and won't get 35 miles to the gallon. Either drive the X5 less, or fork over the fuel bill. It's that simple.
