I was exploring under my hood today, and noticed a BIG area on the driver side front in the engine bay. I started brain storming...and had a thought. That spot is about the right size for another air box! My idea, build a custom tube that brings air from both sides, one from the factory location and one from the driver side. That=LOTS of air for the truck to suck on. It's just an idea, and I doubt I will have time to do that mod myself, thought I would throw the idea out there for someone with more time to mess with.

that's a sweet idea, but I don't think the engine would know what to do with all that extra air, not to mention the mass air flow sensor might go crazy. I really like the idea and think it would be sweet to see but I think you would have to somehow get it reprogrammed to handle the extra air.
