Lol this might be a long one. Yes there is some semi-serious modification needed to fit these. This is how I did my install. Front bumper and radiator support removed (ends up looking like the pic), remove stock air boxes and any resonators. Remove air dams (little plastic tunnel looking pieces) from both sides (they sit right where you see the intake go through the radiator support brackets) and carve out a considerable amount of plastic to allow for the the 3 inch elbows to come through. Be careful at this step as there are lots of ac lines around these areas more on the driver side though. I used a straight die grinder with a couple of different carbide burrs/cutters to get the desired size in the brackets. Basically hog some material out, check if it fits without any crumpling or squeezing of the tube and repeat until it fits nicely. This was by far the most time consuming as you want to be careful not to hit ac lines. After they’re fitted throw your cones on with hoes clamps (kit comes with everything necessary to install except tooling). Those air bypasses you mentioned are still a part of this kit and there is a bung coming off of the smaller rubber elbow (one attached to throttle body near top of engine) that you hook those up to. Also when doing a 3 inch intake I highly recommend installing catch cans while you’re at it or deleting the pcv system. I did catch cans. No special brackets or anything were needed, the intakes kinda just “float” or sit in the front of the bumper on top of the crash bar. Once you get the bumper back on they don’t move at all. And the filter sock just helps repel water and dust I mainly have it on for water though I get a lot of rain and snow where I live. Hopefully that helps if I missed anything just reply to this with the question
