Wow! I bought the Redrock Snorkel thinking it was gonna fit my 2017 JK, but ended up putting it on offer up cause I read it wouldn't fit the 2011+ models. man thanks! I think I'm gonna keep the snorkel and just make that additional modification you mentioned.
Man thats awesome!!! I hope it works out for you!! If you look at my one video of us at the Silver Lake Sand Dunes, its day 3 toward the end, i actually used the snorkel :) Good luck with all your cuts!
It will, just with a little modification to the air box. You will have to cut about half an inch off the bottom and then fill the gaps around it after you install the snorkel.
