TB is throttle body. I saw a 2 mpg increase when I did my fastman TB. Helps if you have some sort of air intake too, anything better then the stock air assembly.

If you're running any kind type ofheaders............never mind wife just called

IMHO, The stock air assembly is way better than an open filter. Think about it. You think DC just had some extra tubing lying around. Or maybe they had some presses with nothing better to do than cut holes in inner fenders. Maybe all the air/ fuel guys/engineers have just been smoking crack for the last 20 years. I really have to hand it to Silver Dodge on this one. This pretty much rivals Burning Rom saying that boost does no good unless you have a MacIntosh under the hood. https://dodgeforum.com/m_376205/tm.htm

Think about this, the air comes in through the fender, has to make a 90 degree turn into the air tube. That air tube has ridges because it stretches and flexes. Those ridges on the inside of the tube do not help air flow, only hinder. Then, once the air gets to the air filter, it has to turn 90 degrees up to go through the filter, then another 180 degrees back down to enter the TB. After all this, can you still tell me that there is not a more efficient way to get air into the intake? Besides, the results I have seen using the round filter assembly have not lied.
So yes, the stock intake may be better in some areas, but performance is not one of them. If the only requirement Chrysler engineers had when designing the air intake on a second gen Ram was performance, then I would wager that we would have seen trucks come out with a much different filter assembly then they did. But they had other requirements to consider.

Well said Silver! If the engineers at Dodge only had to design for performance - I'm sure we would all have functioning hood scoops w/ram air like the old days. I can tell that I have more power with the open setup - and I have been a part of racing and performance cars for many years so I feel I am qualified to make that statement.
If the original factory setup is so good - why aren't they on every race car in the country? The late model I work on makes 800 hp - has the same a/c and filter I have on the truck now.

Way better in what way? Keep in mind that auto engineers have to design every component not just for performance reasons. For example, if every new truck they made came out with a round filter like mine, I think Chrysler would be swamped with law suits from guys who take their truck into mud and get water and mud up all over the exposed filter, so they designed a protected filter assembly. And how many non-performance oriented people who might buy a truck would take it back shortly after and complain that the open round filter is too noisy? So Chrysler designed an insolated filter box that eliminates almost all air intake noise. So the stock air assembly IS better in some ways. But becasue it was designed to meet all these other requirements (water resistance, sound level reduction, gas mileage, emissions, engine asthtics, and many others i'm sure) the performance ability has been reduced. And that happens to be the only area I am concerened with, not all those other areas that the stock assembly may have been designed for.

If you have any kind of headers, especially shorties, you are sucking in some pretty frigin hot air, wich in turn has the pcm pulling fuel as well as timing. Get a cheap scanner and do a test. Put your K&N back on and look where where your iat is. Then look at your timing and your fuel trims at various rpm's. Then put the open air back on and give it a look see. This is the scanner I use: http://www.amazon.com/Equus-3110-Dia.../dp/B0007VXZ7W. I found it on ebay for $99 plus shipping. It will give you most of the engines vitals.Downside is it doesn't do fuel sync.I am going to do a similar test when and ifI get my Ram air box (usps parcel post[:@]). I will run w/ tubes disconnected then with tubes connected.
I do agree that that a round filter has better flow characteristics, and I believe that the closer the filter is to the tb the better the flow. The filter rectifies turbulence, so if it is way up front at the end of a tube, the turbulence has time to redevelope. Especially at the 90* turn on top of the tb. With the stock box or a round filter the air is rectified then enters directly into the tb.
Race cars- Cup cars, Busch cars, and Craftsman trucks use cowl induction, or used to anyway. Not sure about the car of tomorrow. That is not a good option on our trucks since the tb is too far back in the motor compartment.
