Look thats all good, for some its good for others its not, really you either have it or you dont no biggy.
Bugs and very dusty conditions, There's a Pre-filter for that, an oiled foam sock that goes over the head. And it is always wise to use one in extreme conditions with the hat inlet. There are also cyclonic filter heads that use a spinning wind effect for dust and bug separation, these often have a filter in them as well. Right part for the right job.

If somebody is getting more dust in the exact same time and conditions as someone without , I suggest that the vortex is not working correctly in the head. That or they are driving in more dust, or driving longer. Also I have seen poeple that have either placed the hat too far up the inlet pipe, or, cut the inlet pipe off right at the bottom of the hat. It should be clearly visable in the hat sitting up almost halfway it sheilds the intake area. Once again, theres a right way and a wrong way. I have driven in very dusty dirty conditions before and after having the snorkel, and on mine, it works beautifully., regardless of wheather or not it works on mine has no bearing on how it operates on someone elses vehicle. The instant I fitted a snorkel to my V6 it ran better, better pick up, better mileage. I'll be fitting one to my CRD.
Once again nobody is forcing anyone to have a snorkel or not have a snorkel on their vehicle, I'm just a bit sick of hearing that they dont work being their justification as to why not to get one, when in other threads other have said they would get one if it looked better. A decsission based solely on looks over the designed purpose, and if thats the reason, you dont like the look, great dont have one.
I personally dont really like the look of the snorkel, sticking up halfway up the windscreen but then again I also prefer the look of the KJ with the original bumper and a nudge bar over an aftermarket frontbar, but, I have a full steel frontbar because of the dangers of Kangaroos and livestock leaping out in front of me on the highways and outback roads over here, once again , a reason for having it, based on the fuctionality of it. It protects better, gives greater approach angles, and more tyre clearance.
