Engine should be exactly the same.
Exact Engine
Process of installing a CAI is relatively simple and it took me no more than 30 minutes. Your first step should be removing your entire stock intake system, all the way up to your throttle body. Usually kits come with instruction so thats give, although if you still cant figure it out, the way that I would do it is connect your CAI piping to your throttle body first. Clamping it down and maybe using a rubber adapter of some sorts to get a good seal. Install any CAI covers or a box next, and then add your filter head on. At the end of this process, all your left with is connect your MAF and your vacuum hose.
On a side note, I replaced my hose with a breather filter. Doesn't do much, but it is good for the engines health. I hope this is the same process, although I'm confident this is the same engine. I have a 2015 4Runner and my process was way too easy. When in doubt, Follow the kits instructions!!!!

Picked up mine online from Germain Toyota on Black Friday for 35% off and free shipping. You’ll just have to shop around.
Got it installed! Love the sound so far. Wonder what it would sound like with the Borla Touring exhaust?

If you are going to purchase one, use the individual part numbers vs the complete package. It saves you a bunch of money. I also skipped the flow valve and plugged the hole in the airbox with a grommet. (Which is the same size as the one needed for the inside of the airbox)
No issues on the install in my 2020.

Cool. Where do I find the parts list?

These are the parts you will need:
PTR03-35090-AA
PTR03-35090-AF
PTR03-35090-AC
PTR03-89100-AA
PTR03-89100-AB
Vacuum Indicator:
PTR03-34071
I got everything for $205 out the door from Roseville Toyota. I picked it up from the dealer so there was no shipping charge. They were doing 20% off.
You might need to pick up some 5/32 vacuum line and 1/4 inch wire loom for the MAF wires. The parts kit i got didn’t have them in there.
I didnt include the filter. Im using the stock paper one until it needs to be replaced. There are quite a few options if you want to go for an aftermarket filter.

Put a little lube on your grommet and it'll slide right in. TWSS.
Thanks everyone. Shopped around and found it for a really good price (no tax; That's big for me because I live in CA). Cheapest I could find.
Got it for $371 shipped on BAM's Wholesale. Here's the link if anyone's interested...

I get it, but I rather pay more to have one complete package instead of having to deal with potential missing parts, wrong parts, having to buy extra parts, etc...sometimes, the hassle isn't worth the discount I've come to learn.

Did this part fit and work correctly on your 2020 4runner? I have a 2020 trd pro and the website is saying it does not fit the vehicle. Im new to this and just trying to make sure i buy the correct parts. Thanks

Do not know if you bought and installed the TRD CAI. But you might want to forego cutting up your wire harness and you and extender instead, It is a little longer than needed but I tucked it out of the way. Underdog Racing sells them.

When I bought mine for my 19 Pro, it said the same thing. Nothing has really changed inside the engine bay. With that said, save yourself some money and buy the individual components instead of the kit. I think I paid around $220 shipped when I did it this way. I used Conicelli Toyota from PA and ordered online.

Was looking at the TRD cai and came across this ext cable. Got the setup and installed 2 weeks ago on my ‘20 ORP. Sound great when it hit 2k+ rpm.
No issues with the fit, except for a couple of minor nylon strap mounting points that doesn’t match the MY 2012 illustrated instructions, but no big deal.
Didn’t have to mess with undoing existing wire loom when using the UDR cable.
