I took out the airbox to see how the intake tube fits at the fender and noticed that it's a really cramped area. So I decided to add another inlet tube to the bottom of the airbox by attaching 3" aluminum flex pipe using a modified 3" PVC drain grate (cut out the grate). I drilled a 3" hole in the front bottom corner of the airbox then put in the modified drain and slid on the 3" flex tube using a 3" hose clamp to secure it. Next the tubing is routed between the frame and the inner fender liner down to opening that allows
it to be positioned behind the bumper.
The original inlet tube inside diameter is 3.5"x4" or 14 sq inches, the new inlet inside diameter is 2.75" so that's a gain of 5.9 sq. inches. The more air you can feed the engine the better. I bought the materials at Lowes if anyone is interested.
