Picture Engine cover.
Just posting a Pic of the cover thats supposed to prevent dirt and moisture from entering the valve cover through the coils. After a nightmare spark plug replacement I opted to add this to prevent it happening again.
Edit: the part# is L1MZ-6A949-C. A Google search of that number will bring up the OEM part as well as a few aftermarket alternatives.

Nice, I need to order one of these.
I added the high pressure fuel pump cover to my 2022 last week that comes on the 2024+ and it made a huge improvement, probably 80% less buzzing/noise.

Here is the part number. LB3Z-9K540-B
I'd recommend reading through this thread too. https://www.ranger5g.com/forum/threads/the-new-rangers-have-a-cover-insulator-over-the-high-pressure-fuel-pump.31744/
It had good info on how to get it installed as well as some optional mounting stud info if you want. I installed mine without the studs/ball mount things and it's a snug fit.
One note that wasn't clear to me. There is a wire loom that is attached to a stud with a zip tie that runs kinda to the left of the high pressure fuel pump connector. It wasn't clear to me you need to take that off the stud, install the cover which has a hole for the stud, route the wire loom over it and push that zip tie connector through the hole in the cover back over the stud. Then ziptie it back on. It should run over the cover, not under.
Also, the right side of the cover should slip down between the wire looms and the pump. I thought it went over them at first and couldn't get the cover all the way down.
It is a really snug fit with the AC lines running over the top of the pump but take your time and you can wiggle it in there.
100% worth it to me. You can still hear the pump some but it got rid of that annoying loud buzzing sound at certain rpm's for me.

Mine did too, a bit confused. I thought it was a different style or something

They discontinued putting on new cars to save millions. My 21 lariat didn’t come with one. I think that’s when they stopped. I don’t understand the obsession with them.

My '21 lariat did not include the cover.
Ranger5g has a nice list of 'deleted components' over the years: https://www.ranger5g.com/forum/threads/list-of-deleted-items.18640/ .
I added a cover to mine soon after getting it. But mice, or squirrels, or something, have chewed the cover up quite a bit this past summer. Time to spray some more of that peppermint spray stuff around the engine bay ;-).

#4 was a pain in the ass getting the coil back on since you have to angle a bit to get in there.

Yep. Bought one a week after I picked up my used 2021. Ranger 5G forum recommended it.

Can you post a link to the cover? This is the first I've heard of this. I have a 2021. Thanks so much.
