I got bored last week and decided to build a custom intake tube. I found a 4" diameter AirAid U-Build it kit for $99 on ebay, bought a couple of Spectre 4" couplers from amazon, and finally a high flowing drop in filter. This thing was extremely easy to make and I had a lot of fun doing it.

First driving impression, it doesn't take much gas pedal to get the truck moving anymore. That infamous Pentastar throttle lag is still there but is very minor from what I can tell. I took a trip on my usual route to work with the stock filter and intake tubing and drove home. I then installed my modular intake tube with the high flow filter and did the same drive, same weather/traffic conditions. Truck usually downshifts 3 times due to the steady grades on the highway, with the custom setup truck stayed in 8th gear all the way to my place of employment. Also, I reset the gas mileage gauge before I began each trip.

I was stupid and took the photos during different situations, the stock setup was taken while stopped in front of my house, the aftermarket one was taken just getting off the freeway, doesnt make much of a difference though because I live .7 miles off of the interstate. I'll keep y'all updated on the progress if you ask me to.

That looks great! I did something similar using the K&N CAI for the 3.6. I didn't like how it sounded with the open filter so I used just the aluminum intake tube to replace the resonator.

I had a similar experience to you with the resonator gone. I would describe the feeling as sucking a drink through a small straw or one with fruit stuck in it with the stock resonator installed. It seems to suck in air much better with the resonator deleted.

I wrapped mine in fiberglass motorcycle wrap, then metallic duct tape, then cloth tape for engine compartments.

I recently removed my AEM dry flow though after seeing a Project Farm video on Air Filters. It didn't seem that dirty but my MPGs went from 17.4 to 20 after installing a WIX filter.

You should post the links to all the parts. I've seen many people interested in this in the past and yours is very clean!
