BLACKBMW is an unknown quantity at this point
De-baffled my air box today and the sound is great but wondered if the slight increase in o2 would affect fuel consumption?

i havent really noticed a change... but since you are more prone to revving high and getting that sweet sound it makes, your mpg will probably take a hit but thats only because of how you drive

in theory, you should be able to get a very little better MPG number, but nothing significant at all to even worry about....this is just because the flow of air into and through the box would be better than stock, less turbulance would be created...


but like TMac said, you probably rev your engine more, so that will cause you to decrease mileage because of your driving style
