So far, so good!

Plan on 1-1.5 hrs for tuner time and make sure you have a full tank! She will run rich until everything is adjusted properly.

I reused the Volant box and added some 4" stuff. Very basic and straight forward, and the results are wonderful!

Everything has improved, and I think my setup is now about as good as it can get short of boosting it or nitrous.

For the people who are curious, I added a K&N dry filter a while back, and it's truly proven a blessing with maintenance.

Even if you run a standard K&N or Volant, it will work for the setup. Part number is in the last pic. It's also a few bucks cheap than the oiled. Cleanup is a breeze. Soap, water, rinse and dry. Zero oil. As per K&N it filters better and flows more.

How much of that actually translates to power? Heck if I know, but I'm much happier with it and the car does indeed seem to respond better than it did with a K&N oiled.

All in all I am very pleased with the results. I will be hard wiring the MAF adapter harness, and trimming the boots a bit more, swapping them for black ones when I have time and cerakote C7600 coating the tube in April ish.

You will need an LS7 MAF card, harness adapter, 4" MAF mount, 4" tubing 9" length and some clamps and elbows/unions. I'm also welding a bung for the fresh air vent and getting rid of the breather that's temp installed.

You will also need a tune, immediately so plan accordingly, as the car is absolutely unsafe to drive until it's tuned.

Finally reinstalled after some maintenance issues forced me to go back to a stock MAF and stock ish tune.

Now back on the big boy tube and MAF. No complaints and a very noticeable difference between them, with the only difference being the MAF and adjustments to the scale to run said MAF.

Adjusted for better fit and now have lots of extra room.

Last step after getting it dialed in is powder coat the tube black or antique silver. Depends on my mood that day.

I started to do that on mine, but decided the used parts I had gotten from someone here or on LS1tech were a bit too hacked together for my liking. I do intend to get back to it at some point.

Yours looks good, and will look even better once it's coated. The blue elbow would annoy me, though, with everything else in the engine bay being black or grey.

Trust me it trips my OCD hardcore.

I bought a nice black boot and it wasn't exactly what I needed, so I went back and all they had was blue.

End of the day it's functional, so it's good enough until the weather cools down here. I just found some of the leftover cerakote, so now I'm planning on that. Should keep the engine bay heat down.

I am going to give some numbers in metric and some in SAE ('Murica) because it's late, so I'll try and remember to translate them all tomorrow to SAE. But here is a quick review of every Cai I've tried to date.

OEM air box and 4" tube was 75c IAT, dropping to ambient temperature at WOT.

K&N was 175f (only one I remember off the cuff) pretty much WOT or anything in-between. Idle, traffic, crusing etc. It would never drop to ambient temperature as the other do.

Volant box and tube un-heat treated, 165f down to ambient temp at WOT. This is the better solution, though the car "pulls harder" with the K&N. That's my opinion, not a scientific fact. After I insulated the box, it would stay 120-130f dropping to ambient. Car drove much better after that.

The glaring issue with the K&N setup is that they use a steel ring to mount the filter, which the MAF then mounts directly to. This causes heat soak of the MAF and reads higher IAT, which pulls timing due to high IAT temps. The 175f IAT may not have been genuine, and may just have been a heat soaked MAF. I cannot prove or disprove that theory.

The Volant box was the next setup. It did ok, but never felt as good seat of the pants as the k&n did. It's a very good setup. It would be better with a different style tube.

Next I did the ls7 maf setup is 10" long tube with a Spectre plastic 4" filter mount and I used the Volant box. This never quite fit right. IAT stayed pretty low in the 50c range.

Final go round is the same tube, now polished up a bit to theoretically reflect heat a little better, polished the inside to 6000 grit for kicks more than anything else. With the K&N shield. A conical dry filter from K&N mount and new plastic mount from Spectre.

I'll be either powder coating the tube black/silver or cerakoteing the tube like my headers. Depends on my mood when I have the time.

I will do the engine bay side with my leftover intake manifold insulation and hopefully keep things a little bit of a lower temp, I'll be adding a layer of closed cell foam to the edge of the heat shield to hopefully seal up the side a little better. So far this is the best setup I've run.
