I had one on my '08 JK. It's a quality intake. Fits great. Encloses the filter in a box which somewhat helps shield it from sucking in hot air from the radiator, and keeps water off the filter as well. You can remove the lid from the box if you'd like, to open it up a bit more.
I've got one on my 3.6 and it's great. It has a dry core filter and you just blow it out with a compressor. You access it by removing four Phillips head screws from the top panel.
I had the volant snorkel and it was a very nice intake, was going to leave just the cold air portion installed but decided to go back to stock for a while. Deff a nice intake however and very well made. Never had issues with dirt but i also ran the pre-filter sock thing on it.
Got the Volant with PowerCore filter in my '09
Very happy with it...... the PowerCore filter doesn't need changing till 100k or 4 years in normal conditions. I'll probably swap mine out in half that time due to the dust/sand here but not complaining.
Easy install and good quality.
