Seems that the previous owner swapped out the stock filter and replaced it with a K&N. I'm a newbie to the jeep world, first time owner. Thing is that the filter has no support to keep it in place. It's just resting on top of the rest of the the things. Is this ok? Do they sell a support for this? I looked at several kits, and it seems that all of them come with a plastic cover around the filter, I'm assuming this bolts down supporting the filter. Thanks for any feedback.
