So I was out tinkering and decided to check and see if I could improve the factory intake any. I pulled the front part of the intake apart ( that is mounted behind the grill) and add a new intake path. From what I found is that there are two intake areas where it pulls air in from behind the grill. Only one of ours is used and it's on the passenger side with a flapper assembly on it. The other side is blocked off which leads directly into our airbox. So I cut mine out and sanded it down. I hope it helps besides making more noise. I'll try and post up some pics explaining what all I did.
