Just remember, none of these intakes have been dyno proven by anyone other than the companies trying to sell them.

 

^^^ exactly

no one knows for sure who's flows the best, filters the best or has the most high end/low end power..

one might make 6+ hp at 4500 rpm but might lose 15 lbs of torque at 2100.... so without dyno numbers its all a guess

 

Without dyno pulls and measuring your A/F ratio, the stock air tube is fine, you do not want to change the MAF sampling area without measuring your A/F ratio, especially at WOT. All we can do is open the end up for more air input for now as there are no tuner/intake packages available ( this is what I miss from the Ford F150 tuning ). Keeping the heat shield/air box is good so you do not get heat soaked off the line.

 

The only problem with what you said is that we do not have a MAF sensor, we have a MAP sensor. They are two completely different systems.

Here is some WOT information.
WIDE OPEN THROTTLE MODE

This is an Open Loop mode. During wide open throttle operation, the PCM receives the following inputs.

• Battery voltage
• Crankshaft position sensor
• Engine coolant temperature sensor
• Intake manifold air temperature sensor
• Manifold absolute pressure (MAP) sensor
• Throttle position sensor (TPS)
• Camshaft position sensor signal

During wide open throttle conditions, the following occurs:

• Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control the injection sequence and injector pulse width by turning the ground circuit to each individual injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined amount of additional fuel. This is done by adjusting injector pulse width.
• The PCM adjusts ignition timing by turning the ground path to the coil(s) on and off.

 

With a little ingenuity an elbow and a conical filter I can't see why someone can't just make their own cold air box.....the airaid is a copy of the original box without a lid and fitting a conical filter..so to me the original is already a cold air box is it not, it gets the air from the exact same spots...if you don't buy the hose with it just think about what you really get and for how much.

 

Just a heads up...JC Whitney has the Airaid 2009 ram Cold Air intake for 230.99 less 15% and free shipping. It is the kit w/o intake tube. not bad for under 200.00. Sale ends on Thursday.

 

im with you 72 combo. why doesnt it have a lid anyway?

 

It comes with a section of stripping that attaches to the top of the box and uses the hood as a lid for the enclosure. Works well.

 

As the starter of this thread I want to thank all of you for your input. The last few replys were very interesting regarding just puting a good high flow filter in the box that came with the truck. My only question now is why a conical filter? What advantages does it have over, lets say, a K&N high flow replacement filter that is around $50-$60?

We just resolved a big ordeal about CAIs (in the 2nd gen section). They are not CAIs, wherever the air is drawn from. When the air comes into the intake manifold, the air is heated by the hot motor and even heated more when it goes into the Hemi head. By the time that the air is in the combustion chamber, it is not cold, and will not have an effect on the performance of the combustion. More air > Cold Air.
