DeathMetalTruck,
I see what you are saying but dynos aren't representative of actual on-road conditions either.

While it is true that a closed hood will result in increased underhood temps on a truck that isn't moving, there have been several members on this site and others that put temp probes under their hoods to measure the temps on the road.

The results:
When the vehicle is not moving, underhood temps do rise.

When the vehicle is moving, though, enough fresh outside air is forced underhood that the temps are just a little bit above ambient.

 

Yeah I def see what your saying there. Makes sense. Either way all my point really was is that I don't think your gonna get nearly as much gains as any of these companies claim.

 

I installed my AF1 it was very simple, did not even need to unplug the battery and none of the warning lights ever came on

 

This k&n doesnt show a heat sheild, i suspect it does come w/ one. all my searching has yeilded little results it always brings up everything w/ CAI or cold air intake in it as well as k&n Im thinking this is the intake most ppl are talking about when they say 77 series, correct me though if im wrong.

theres one without the heat shield and one with the heat shield. make sure youre getting the one you want. i got the one without the heat shield.

 

I would go with the AEM Brute Force, I found it at autoanything.com for $296 but input GIFT10 in the coupon slot and you get it for $267.25 free S&H
I have always been a fan of K&N but through my research I have found that the AEM will produce better results. Either way I'm sure you'll be pleased.

 

They also say the Airaid is the only other intake that does not cause a lean condition with the engine.

 

If I had to choose between K&N or AEM, I would choose the AEM.
