CAI will lower your fuel economy drastically.
The roar sounds SOOO good you start gunning it every chance you get. Dropped my fuel economy down to 12.5 MPG. Took it off and went back to stock and its back up to 14.5
I think it was my changed behavior that did it, and it had nothing to do with the actual parts.

The stock OEM air box`s are tuned very well to these 4th gen trucks...!!!

You can squeeze out a tad better fuel economy with a CAI but not by itself. Think of it like the old "chain is only as strong as it's weakest link" adage. You'll benefit by the added surface area of a cone type filter BUT only if you port the throttle body to accept more airflow AND then you need to consider an intake manifold with runners that can make use of the extra air coming in. NOW you need to consider the natural backflow of exhaust into the cylinders at the exhaust manifold so you'd need headers to properly scavenge this air. Of course now you have to think about the cats, any restrictions in the exhaust such as pinched "Y" pipes and possibly the muffler.
My point is that it is possible to get a tad more MPG (and about 30 or so RWHP) by completely redoing the intake and exhaust BUT you'd better plan on owning your truck for about 30 years or so to make up the cost of the mods in fuel savings.
The only real modification I've seen that doesn't take a crazy long time to make up it's cost in fuel savings is going to an e-fan. They aren't terribly expensive and are quite easy to install without having to pay for labor. Of course, the benefits of an electric fan are seen most in town where you start/stop and accelerate from a stop or slow speeds often. An e-fan losses it's physical advantage over a clutch fan on the open road where engine RPMs minimize the parasitic loss a clutch fan causes at low RPM.

So i just bought a 2010 Dodge Ram 1500 Reg Cab, 2WD, 4.7L, and i am looking into modding the truck, id like to try and pump out atleast 50 RWHP.
im still learning about the truck so i would highly appreciate any and every input possible!!
ive done some reading, and came to find out that theres not too man mods for the 4.7L
Also a questions that i had was if i could install a LSD?????
