I just finished installing a Nismo cold air intake on my 2023 Performance Manual car. There is not a lot of information on line with details on the installation, and the Nismo kit came with no instructions. I checked out the AMS instructions, unfortunately they are incomplete with missing images and missing details. Watched videos of people attacking the job from under the car, another one from the wheel well, and also from on top, and I wanted to report on my findings:

No easy access from the wheel well (at least passenger side) that I could find.
Some access from underneath the car on both sides, more on driver's side
Best access is from up top. On the passenger side it is not great, and challenging.

Driver's side install took 45 minutes, and is easy and straightforward. First challenge is removing the air boxes from both sides. They are held in place with 2 Phillips head bolts that screw into the front apron of the car. This is the easy part. The challenging part, until I found the right tool is releasing the spring clips that hold the airboxes to the inlet tubes. The best tool that I found was this: https://www.harborfreight.com/2-pie...r-set-65772.html?_br_psugg_q=long+screwdriver Once I got this set the springs were released within 5 minutes, easy.

Working on the driver's side you remove the MAF from the stock airbox and set it aside. Then with some finagling and a long 8mm socket on in my case two extensions, you can remove the clamp holding the inlet tube to the turbo. Installing the new tube was easy. Use some grease it does ease the installation some.
Be careful to position the hose clamps as the original ones were set as this makes access easier.

Now on to the dreaded part, the passenger side. This took me about 3-4 hours of dicking around with the PCV connection, and trying to get the tube on the turbo. It is ridiculously tight around this turbo, and the access to the clamp is more difficult than on the driver's side. Once you get the OEM tube out, careful to position the clamp on the turbo side of the tube, like the OEM clamp, and install the PCV tube before installing inlet tube on the turbo. There is minimal room to work and rotate the tube in the correct orientation. Again use grease to ease the install. You can gain some access to the tube connection to the turbo from underneath to orient the tube, but prepare to get your hands and forearms scraped up. Once the tube is in place and oriented correctly, it is Miller Time. The remainder which is installing the passenger side box takes some finagling again and some forcing, but in the end it works, and that part only takes 20 minutes.

I would definitely watch the videos out there, and read what instructions you can, but prepare to use some parts from all to get these installed. When you watch these videos, they conveniently skip over the passenger side install,. and you will find out why.

Good luck. Hope this helps someone.

When I saw how painful the install was, I decided to avoid the AMS / "Nismo" CAI.

I had one on order last Christmas when it was $407 but was on backorder and I ended up canceled it as I had some life stuff that came up. NISMO is supposed to send me one to quality test during my autocross events but I would not do the install myself. I have just Hi flow drop ins right now and really am not in a rush for the CAI. If they do send it out there is a Z oriented tuner shop near me I will probably have do the work

I got the Z1 CAI, and had Nissan specialist install it in my garage. My hands weren’t small enough to get to the clamps. Also wasn’t sure how to disconnect the wiring harness’s. Note: Withe the Z1’s you have to remove the boxes to get to the filters. They are washable, but getting to them is a pain. Worth it though! 😊

I was about ready to give up midway, and lucky I started on the passenger side, but when I went to reinstall the floppy OEM tubes, I realized that was even more challenging.

I have to be honest, I am not a huge fan of CAI's,- and I think they often just add intake noise, which I am not interested in. Review shows it adds 15hp, and is quiet with the full box installed. I am also adding a tune, so hopefully will not add noise, but will add a few Hp.

Sorry to hear that. I installed the Armaspeed intakes without too many issues. Getting those spring clips off was the hardest part because I didnt have a long screwdriver but overall pretty easy.

Likely more skilled than me, or much smaller hands

Hmm yea I was gonna ask about the size thing.

I'm not particularly skilled and only do basic intake/exhaust installs. But I do have a slender build and slender hands.

Anyone able to compare it to an R35 intake install? That one was one of the more challenging ones I've done but still do-able in my driveway. If it's like that or easier I can handle it. More difficult and I'd be a bit worried.

But it's always so hard to tell. I was worried about the exhaust install because I saw a car youtuber doing it and they had 2 extra helpers and removed a whole wheel to get more space and still said it was really hard.

But then I did it myself just on ramps in the street. Same exhaust and everything.

Also unrelated but I was gonna go with AMS but they actually require you to race your car at events to buy parts from them now. So I guess I'll be going with Z1? Unless there's an option out there that allows you to swap the filters easier?

Edit: ohh I see Mishimoto has one with a removable top too. Hmm.

Yeah the AMS waivers are annoying but you can find their intakes at other places who will sell no prob.
