I decided I wanted to swap the intake on my 2017 Gen2 Coyote to a 2018+ Gen3 intake. I watched a few intake comparison videos and it looked like a gain of around 30HP is possible on the top end of the power curve. The trade off seems to be some torque on the low end, especially when in high gear with the IMRC delete. I don't really want to debate whether or not the swap is worth the effort, but rather wanted to detail the process, particularly in how to reuse my painted Gen2 cover with the Gen3 intake.
Here is a shot of my stock 2017 intake with the painted engine cover in place.

This is the 2018 intake as it came out of the box. Notice the CMCV/IMRC units on the back, they will be deleted. They were just in the way of my engine cover and my tuner thought their benefit was negligible, so I decided to just remove them.

I removed all the IMRC hardware and cut down the plastic boss that holds the pigtail connector with my dremel. I found some inexpensive aluminum IMRC lockouts on eBay for about $18. I powder coated them black before install.

The attachment points on the Gen2 cover do not line up with the ones for the Gen3. I pulled out the rubber sockets and made some z-shaped standoffs out of 16ga steel (1/16" thick). I bought the steel at a Metals Supermarket and they cut them to size for me. I used my vise, a torch, and a hammer and punches to bend them into shape. These standoffs basically raise the rubber sockets 1/2" from their original height in the intake. Here they are after powder coat.

To get the brackets in the proper position, I laid down some painters tape and snapped them onto place on the cover and just set it up there and aligned it by eye. Once it looked good, I marked the back edges of one of the brackets with a pencil, removed the cover, and then marked that bracket for drilling holes. I intended to mount the brackets with rivets, but I didn't make the edge of the bracket wide enough so I used some SS machine screws, washers, and locknuts instead. If I had to do it over again, I would make that edge where it mounts about 1/2 - 3/4" wide so I could just rivet it in place. Once I had one bracket mounted, I placed the cover back on it, marked the next one, and repeated this process until all four brackets were in the proper position.

And here is a test fit of the cover. It sits about 1/2" higher than on the stock manifold, but does not look too bad and no need to mess around with cutting down a Gen3 cover and getting it painted.
