well just drove my '02 GLE with berk intake about 400 miles mostly staying around 70-80 mph (cops in texas hide in the damn bushes too), and my MPG went from 19.6 and it peaked at 21.6, which i didnt hit until i was back home, so is this a good increase or should it have been better?

 

any increase at all is an improvement. 2mpg extra aint bad at all just for a intake.

 

naw that sounds about right...2 miles per gallon is great actually...people LOSE gas mileage with intakes, generally...haha

 

yup, you usually lose a little when you put an intake on. Maybe you had a really clogged air filter in the first place!

Hate to disagree but when I added my berk I gained about 1 MPG. I think most notice a drop in MPG with an intake because they are always driving WOT to hear the sound.

As far as highway miles, 21.5 seems low. Our Murano (3.5 VQ) gets 24-25 on the highway, and my I30 (3.0 VQ) with the Berk intake gets 28-32 MPG on trips.
