The primary reason I purchased the Ram Air with the Super Scoop was to increase fuel mileage on my 2011 Silverado 2500HD. I drive back and forth to Atlanta from the Tampa area every 6 weeks. My truck would average 21-22 MPG prior to installing the Banks Ram Air.
I installed the Ram Air on Monday and drove to Atlanta on Wednesday. No change in the fuel mileage. I drive 75 MPH using the cruise control. No change in the average fuel mileage.
The installation of the Ram Air was easy and straight forward. The installation of the Super Scoop was not as easy. The photos in the manual are terrible and hard to see details. If you are do not have good mechanical skills you may have problems.
Also the hose clamp that Banks supplies to secure the air filter to the ram Air housing was not the right size. My air filter is held on with wire ties until I can get the right size hose clamp in from Banks.
John at XDP was very helpful.

Bought this product because of one simple fact when it comes to safe and reliable power Banks is #1. Before installing this intake and a Banks 4 inch Monster Exhaust I was getting about 15.5 hwy and about 12.5 city. But I'm sitting on a Rough Country level kit and 33.1250.18 toyo m/t's. After installation it boosted me up to 15 city and up to 21 hwy. No programmers or any tuning either. Things to come in future MBRP turbo downpipe and maybe Banks Automind.
MORE TQ and SOUND but NO MPGs

good power for my 2011 LML NO PROGRAMMER. They don't offer the superscoop for the LML but I bought it any way. It doesn't mount with the given hardware so you need to be good with your hands. If not, do not get the LMM super scoop. I got it mount on one panel bolt at the bottom of bumper. Had to drill about 2 or 3 holes and heavy duty zip tie for the upper. Some heavy duty rubber to snug up the connection to the filter box. And I also sealed up the big hole on the side to keep hot engine air out. Long story short 50 MPH - 27 MPG, INTERSTATE AT 70 MPH 24.4 MPG on the dash read out with 50 degree weather. better than 19.2 MPG AT 70 MPH. I put 1/4 a tank in cruised the highways for about 2.5 hours. Burned half of the quarter. $159 for the LMM super scoop and 5 EXTRA MPG... No Bull Not sure about my power gains but its still strong as an OX.
