well you do have more fuel, do you think the injectors are maxed out on a stock jeep

all im sayin is going to all the work to cut out the hood to clearence for a durango air hat is pointless, no better than the stock one,

in a case where you have a ported intake and headers, your next step is a throttle body, and why would you put an upgraded throttle body with a stock restrictive air hat?

as towards temperature, yes it is metal, no it doesnt get hot, as in you can touch it without burning yourself as long as you have it routed so the filter takes in flesh air

The comp auto adjusts for the air which is marginal at best. If you upgrade the inside larger injectors better everything. That 4 in air hat is awesome for a race motor, thats bout all tho

I install a Spectre air hat and it stays very cool until the engine is shut down and everything under the hood heats up.
From my understanding the only gain will be at WOT where I'm seeing -3in Hg and sometimes -2in Hg inside the intake manifold.



I also have a custom 3" exhaust system which I understand is good for a 700hp engine, and also installed a performance ignition kit.

After spending $1000 for these upgrades, I can't honestly say that I have notice any more performance over the stock setup.
In the next year or two I will be rebuilding the engine and throwing on new heads, new cam, along with a few other items, and then it will all come together to make a difference.

Only those who will risk going too far
can possibly find out how far one can go.

Your stock mopar computer won't give you more fuel because you have a different air intake.

right- it just keeps it mixed right. the stock ones can be tuned up for a bit more performance through the pcm, not much to be gained from them tho

it does keep it mixed right, you give it more air, it matches with fuel, results you wont feel but it happens

I installed a mini ice maker in my air box so that I get the coldest air possible.

Did you use newb tech on the minifridge? 5hp increase at least.

The Durango SRT airhat with variable flow fuel injectors to include all advertising will net you 87.2 more hp and 90.6 more ftlbs torque. (I read this on JU).

Take your throttle body off and bang it with a hammer. The dents create a triple expository intake characteristic (often seen in tornadoes and hurricanes) which allow you to run your engine without any oil, therefore decreasing weight and freeing up about eleventy hundred horsepower at 14 RPMs.

Exactly my point, I don't know why more people aren't doing this!

I also found that using porch screening on the intake hose instead of a K&N flows even better and frees up that space where the filter used to be.

I also have a leprechaun that looks like this inside the TB for that extra get up and go.
