If you are really wanting a K&N intake, you can check out their site and they post the dyno results on a 4G Ram... www.http://www.knfilters.com/
For a 2011 1500 with Hemi they post these supposed gains:
63-1561 - the plastic tube kit
Estimated HP: 15.66 HP @ 4688 RPM
77-1561KP - the metal tube kit
Estimated HP: 10.3 HP @ 4382 RPM
I've also heard and read a lot of what BlackHemI said that the metal tubing retains and absorbs more of the engine compartment heat which is kind of the opposite of what you're installing an intake to do. I just received my 63 Series K&N Intake from UPS yesterday, got it two day shipping and tax for $244 from Amazon.com. Going to be installing it tomorrow. I like the look of the chrome tube in the 77 series, but cooler air is the goal and besides, no one can see the chrome under your hood when you're passing them!
