Here are some before and after pics of the banks ram air c.a.i. Installed on my armada, after a test drive i noticed alot more crispier throttle response and it also pulled alot harder when shifting from 1st to 2nd gear. As for m.p.g. We will have to wait and see after going through a couple tanks. I will keep u posted! Also i took a shot of what banks is claiming their product can do. I am very happy with the install and results i got. And would recommend this c.a.i. To fellow club armada members.
