Thats why I made my own sealed pipe into the airbox passage......theres no way for a scoop to create pressure if the air has the opportunity to come back out, where as the pipe forces the air in and cant come back out!

My Ride: 2008 535i LCI with sports/premium package, Sports trans with paddle shifters, CF emblems, JB4 Software, Dinan Exhaust, Navigation, M5Tech body kit, Carbon wrap interrior trim and CIC Controller.

I have a 535 with a JB4 tune and get a constant 24-25 running around. Most of my driving is highway. When on trips it goes up to 27-28. I'm not heavy footed, but I would say I drive normal. Can't complain at all about mileage.
