There's 2 plastic pieces, the wide radiator cover in the front with an air scoop and the air duct that tunnels air from the scoop right in to the hole in the skid plate. Which is the part I think the OP posted. I suspect most 4runners are missing this piece because it gets tossed in the trash by the tech doing the first oil change.
The scoop and air duct are part of a "spolier" appearance package from what I remember so I think are essentially useless. That wide radiator cover is there for some good reason though because it comes on all of them.

Interesting. I bought my 2016 new and have done all oil changes. That "scoop" wasn't there from day one. The hole on my skid is open to front with only wire mesh in it. Now I'm curious and will have to start looking under the fronts of parked 4Rs, although that might look odd. 8^) Thanks for info.

This must be an older 5th gen 4runner or other gen 4runner. I installed the TRD skidplate on my wife's 2020 4runner back in July. The standard steel skid plate, which sits under the oil filter, was replaced with the TRD part. The TRD/Toyota instructions said to not reinstall the other plastic cover that Saker posted. I found that odd, but my guess is they said not to reinstall because plastic cover would need to be modified to fit like Saker noted.

from a 2015 Limited. The air duct piece (Engine Air Intake Hose 5281235010) and the horizontal piece (Radiator Support Air Deflector 5210135700) both need to be removed before the regular skid plate can be removed. You can see one grey, round plastic clips on the Engine Air Intake Hose. I have "trim tool" to remove those. They are difficult to remove with out the tool. Its not much hassle with the tool. I like the protection these two covers provide. I thought the air duct piece/hose was only on limited awd and the horizontal plastic radiator support air deflector was on all models. Research shows Sr5 with the "appearance package" also had the Engine Air Intake Hose.

What's the gain from leaving it off? 10 seconds? I just put everything back in place. It really isn't hard to do.

I was on the Toyota TIS today and looked at the Repair Manual section. Under the oil change procedure it had you taking off the Engine Under Cover Seal. Then to “REMOVE COOL AIR INTAKE DUCT (for 4WD with Intuitive Parking Assist System)”,
Going to the link provided for this it shows a drawing of this duct.
So it seems the Limited models which have Intuitive Parking Assist (parking radar?), and have this cover/duct to channel air to help cool the system I presume.
OP, you have a Limited?

I worded it poorly but it's explained with pics further down the thread. The scoop and duct are pieces of the same package but the scoop is clipped to the radiator deflector and doesnt need to be removed to take off the skid. The tunnel annoyingly needs that pry tool to get off to do an oil filter change. Long story short you aren't missing anything.

Can you please tell me the tool part number to remove those plastic clips?
Thanks

Never had this piece on our 2014 SR5 and I've done all the oil changes. Installed a TRD front skid plate and removed the plastic piece that went between the old skid plate and the front bumper. Still have it and would be happy to sell it.

From reading all the comments on this Cool Air Intake Duct it looks to me that the consensus is that I don't need to worry about replacing it on om 2012 SR5. Do you guys agree?

I'm new to our 4Runners since I just bought my '23 Limited back in September and have only done one oil change since I got it but it looked to me like it may be a cooling duct aimed at the front diff since the rest of the cover blocks the air that would cool the front diff.Just a thought.

I have been running without mine and I have had zero issues. It actually would hang down on my 2012 limited and I removed it as well as that black plastic trim below the bumper to have better access to my front recovery loops. I have the factory skid plate and that air duct guides air through the mesh of that front skid plate. if you remove it air can still get through but maybe the odd leaf etc. might get stuck in there. I've driven through deep snow, mud, water and it's fine don't worry about it

I took a few minutes and cut mine on both of my T4R's and put them back on. When I remove my TRD skid, trim stays in place. It doesn't get in the way

Radiator is above that, so it has no effect.
