There are 2 main things why that video doesn't apply to us... 1) the first vehicles stock airbox had an intake tube on the engine cover... On pre 97 XJs there is also a hole in the front end that directs air to the airbox. On the 97+ xjs there isn't a hole next to the radiator that directs airflow to the stock airbox. 2) each vehicle accepts more airflow differently. The jeep 4.0 happens to be able to accept and use more airflow. You will notice power that lasts longer in accelerating and going up hills. You will also notice slightly more on demand take off. But the pod intake or cold air intake Is most effective on 97+ xjs. Even more effective if you run a hood scoop to it.

Drivers side scoop actually functions to direct air into the intake pod filter.

Another thing. Air flows with more velocity thru a metal tube rather than a rubber flexable hose. Imo tbs is a waste of money not a cai

Well I installed my spectra yesterday with a power aid spacer, I need to find metal pipe I had to use the factory tube for now. I noticed a slight difference in mid range power, and nice whistling sound just before tranny shift

Yeah you drill or cut holes on the driver side of the air box. Do it below the air filter so the air still gets filtered. It allows more are to get in to the engine just like a cold air intake but it is free and you can still use stock air filter.

Was your air filter dirty before you changed it? What you noticed was an increased throttle response not power increase. The proof is in the puddi.

I fail to realize how this would make the video not apply to JEEPS.
The second car should apply then right?

NO you are wrong all engines react the same to more air, by producing more power.Turbos and superchargers give the engine more air thus giving it more power.
The second car should diffidently be able to accept and use more airflow because it has a turbo which produces more air flow than a CAI.
A hood scoop with a CAI is like a ram air intake which forces air into the engine making more power because you are getting cool fresh air forced into the engine.

I hate to continue to tell you your wrong... But.. ok leme start out with no I had a new k&n, second, no the second vehicle also doesn't apply bc its a peformance moded turbo sti motor. Next no all motors do not handle air the same, on most smaller motors if you add more air intake, but leave the exhaust system the same output you won't see Any effects bc they are engineered (most newer vehicles) to use the maximum exhaust output that the system to handle. On the xj, zj, wranglers, mj, the vehicle only uses ~80 percent of maximum exhaust output capacity, thus you have ability to increase the volume of air moving thru the mechanicsl system indefinitely. That's where a pod filter comes in handy. A pod does not In all cases result in more performance but In vehicles like the xj they do they allow more air to enter than the stock set up thus using the maximum air capacity that the system can handle... Feel free to fire back.

I agree with using the swiss cheese box only on pre 97 vehicles because of the air directing passage in the front end.

Like a garden hose if you turn it on regular some of the hose ( jeep exuast pipe) is not being used. But if u turn it on high (adding a way to get more air into the motor like a pod) its now maximum performance.

I would get a "heat shield" to seperate from the rest of the compartment, and plug the holes below it to control water splash, as far as a pipe I'm not sure where you can get one seperate.. measure the outside of the throttle body and head to the hardware store and see what they have, might need to do some bending.

Sorry I can't prove my education to you. I can vouch for all my buddy who is a technition trained to work on sti motors who was here earlier and explained how it works to me, hes been in auto school for like 6 years, ford jeep Honda Subaru, viper certified. He knows what he's talking about and I trust him

I need to find a heat shield, water splash is controlled by the bottom of the factory air box that's still installed. Wish I could find a pipe that has the valve to hook the Pcv into.

Did u see how mine was? Filter was connected to a metal tube to keep it in position, then the metal tube is inside a short bit of smooth rubber tube that attatched to the throttle body with a clamp

Yes and it looks good, I gotta find some pipe to fix mine with, it just clamped straight into the factory pipe
