Since Kuwait has more dust I would go for the AEV snorkel. Their snorkel has the dust separator. It should work well with the K&N to help to reduce the amount of dust, increase the life of the filter, and also increase the cold air going into the engine. If you go with a ram air type filter it will not decrease the amount of dust as much.

Literally everything is a compromise. If the K&N filters are able to move more air, there is a reason. That reason is less restriction. What is the restriction in an air filter element? That's right folks, the filter media. Less filter media=more dirt in your engine. The K&N filters can boast about increased power, because with less restriction, they allow more air to move through the filter element. They also allow more dirt. To begin with, this is a dead horse that's been literally beat into the ground. The stock air box assembly is not utilized even 100% of it's flow capacity. This is why adding an aftermarket filter or intake system shows little to no power increase. The 3.8 engine simply does not NEED anything other than the stock box. If it did, you would see more across the board claims to power increases by changing filter elements and or intake boxes. Most of what you think is a power increase is simply noise from a more open air intake box and nothing more. Most people think since it sounds faster, then it has to be. For those who say that mileage seems to have dropped off after adding an aftermarket filter element or intake box, why, of course it would! Because you like the new noise so much, you're gonna be puttin your foot in it more so it'll make that noise. The last time I checked, mashin the gas pedal more didn't equal better mileage. So, does this mean all of K&N's stuff is junk? Of course not. It does mean though that before you make any changes, you need to be informed of the facts first. The fact is in this case, for the 3.8 in the JK, adding an aftermarket filter or air box doesn't add up to horsepower and mileage gains as some manufacturers claim. In fact, it can lead to engine damage through valve seat recession from injesting too much dust and dirt as well as a hydrolocked engine, from getting water into the engine, which your warranty will NOT cover. So, buyer beware.

The prob is i dont like the aev snorkel even with the ram air type filter. the RR looks great and is metal, with our heat no matter what the plastic with time il see the heat working its magic. i think the RR with the stock air box will be good for dust and everything rite?

I don't know if you folks have ever checked out jeepforum.com, but they have periodic Q/A sessions with Jeep engineers, and during their wrangler discussion they addressed this situation specifically.
In summary they stated that they tested various filters with the 3.8L motor, and determined that the engine would not take in more air with a high flow filter like a K&N, and that the only thing that would happen is to decrease the longevity of the motor.
If you haven't read the thread it's an interesting read. They addressed many questions including why they chose the 3.8L motor. (If I remember correctly, they stated the reason was due to the long block hampering crash tests, nothing to do with mileage or pollution ratings)

It will help if you are traveling close behind a vehicle, but it will not help if you are not since the dust in the air will still be sucked up. I know in Moab I have seen people have to empty the prefilter 2 to 3 times per day. With a ram type snorkel this is the stuff that would go right to the other filter, and with a K&N drop in it will not stop this from getting into your engine as well. I know I heard the RR is also coming out with a model with the prefilter, so if it is a design thing that you like theirs better then I would wait or talk to them about getting it with the prefilter.
