I think that will definitely help get air to the filter. When it comes to water fording, you just need to make sure your careful when the front end of the XK enters the water (make sure its not over the bumper) and when crossing make sure the wake of the water doesnt come over the hood. Other than that theres really nothing to worry about especially since you took care of the bottom of the filter that was wide open. I think the only place that you would have to worry about in our upcoming trail rides is Lake Christy if you attend the Rausch Creek trail ride. Last time I was there I crossed it without having a snorkel and I had no issues. I just stayed to the far right where the water wasnt as deep. The best part is if you dont feel comfortable you dont need to take your jeep in there.
