I vote save your money and stay stock.

 

Yeah, I was thinking an entire bushing kit for my vehicle and some new hoses and stuff.

 

You can get a complete poly bushing kit for $99.99 to $150. And they make the worlds of difference in ride quality.

You could always run a line into your passenger cowl and get a CAI that way. And there is a filter that can fit in the cowl too. I need to look it up again to remember which

 

You guys realize you CAN'T do cold air on these right? The header is practically designed to heat the intake manifold. You're just wasting 300 bucks. If you want a less restrictive filter, just get the K&N panel for the stock box, and hollow out the sides. ...and no you don't have to worry about turbulent air seeing as the throttle feeds straight into a flat wall on the bottom of the Manifold.

The only way to really increase power on these blocks is forced induction. Nitrous Oxide is only a temporary rise and will break stuff fast.

 

The only thing close to a "true cai" for an xj is a snorkel

 

Not even that. It doesn't matter where you get the air. You could run a snorkle down to Antarctica and still get nothing but hot air to the combustion chamber. You can wrap the headers and vent the hood to your hearts content but it isn't going to make a difference. Get over it and stop wasting your money.

 

U can make a cai, for like 25-50 bucks and its basically the same as those name brand ones and does the same thing

 

That's only partially correct.

You realize that that the air in the intake is not in it long enough to warm up a substaintial amount?

If your arguement were true, there would be no need for a Manifold Air Temperature Sensor.

The air temperature does rise and fall. This changes the resistance of the sensor which in turn changes the signal to the PCM. The PCM uses this input (and others) to adjust the injector pulse width.

 

i've been running the AEM for a couple of years now, its awesome on the road, it delivers a real deep growl when you get on it, and i'm convinced it gave me a little extra pep in my step... for offroad purposes it probably isn't the best bet and neither is the AFE. i have to be careful with the holes that i hit and when i do i have to go somewhat slowly to avoid splashing up mud and soaking the filter with crud. if your not worried about that kind stuff then just disregard that. the AEM is a good simple set up with a filter that is supposed to last forever, just gotta clean it with some soap and water every now and then.

 

Yes the temperature does fluctuate but it still isn't cold. The difference is seriously SO minimal that I'd be surprised if the temp sensor even noticed enough of a difference. To alter mixture further. The air traveling through the CAI is still surrounded by the rather high radiant heat all the way to the manifold. I promise that anyone who claims they feel a difference, is simply feeling a psychological change accompanying the hype and expectation. If anything you're simply feeling a quicker throttle response. Its so minimal, that your **** dyno couldn't feel it. Even GoJeep's writeup on a higher flow intake tube has nothing toward cold air.

 

AFE was ordered yesterday

 

The key word here is INTAKE.
The product is Cold Air INTAKE.

Not Cold Air All The Time

A quality CAI can provide horsepower and torque increases but they don't do much for a Jeep at idle.

Air temps will be higher at idle as well since there is little air being drawn through the IA openings in the TB.

Open the throttle and that is no longer the case. As engine RPM's increase the volume of air passing through the manifold increases as well, and so does the velocity of that air.
