Alrighty, working on getting the dimensions and such into Solidworks and then we'll get them programmed into Mastercam to machine out a prototype for the MAF Tube and MAF Adapter.
Looks from the likes of this thread that there is interest in 3 main things:
MAF Adapter for custom or replacement intakes (with options for filters)
Replacement MAF Tube to drop in your existing sensor (2.75" and 3.0" options)
A complete intake kit from TB to filter (short-ram and cold-air options)
I will buy the 3" MAF tube from you. I have been wanting one for some time now. I am going to purchase a new braille battery and put it in the trunk then get a cold air intake made for my car along with a JWT pop charger air filter put on the end. I have the money waiting for the product right now.
I have decided to stay with the stock airbox using the GAB and OSCAI mods. However, I feel a billet MAF tube would have better flow (smoother inside) than the stock one. Is the MAF tube going to be the same length as the stock one for those of us who want to stay with stock airbox? If it fits right in place of the stock MAF tube, I am definitely interested.

We are planning on doing a CAI and short rams that would just require you to drop in your original MAF sensor, aside from the MAF tubes.

The MAF Tube could be the same length, however it would have bead rolled ends in the production version. We could do a one-off where we would weld on a flange so that you could bolt it up to your stock Airbox.
Since your making a MAF tube, MAF adapter and also considering CAI/SR intakes in different sizes, im realy interested in seeing what configurations you would be willing to produce.
I would want an intake that uses the least amout of connections (as in as one-piece as you can get) while still having ease of installation. Maybe an intake configured like mine (pictured below)
where the most difficult part of installation would only be relocating the battery to the side (as oppose to cutting a hole under the fuse box which is much harder). Maybe a heat shield will even be better!
All in all, im kind of speaking for myself, its all dependant on the crowd, but i think you realy need to lay out the exact options and post a poll.

Please keep it updated because I will buy one. Any estimation on what kind of price we are looking at for a CAI? The MAF sensor flange will be welded onto the intake right?
Also interested in 3" ID short ram intake if you make it
Great.

We will discuss some potential ideas before it goes into production to get feedback.

Yes we will be making this as comprehensive a solution as possible. Meaning that the MAFS will be bolted (dropped) into the new piping. No idea on CAI or Short-ram pricing as of yet. Will be making the MAF Adapters and individual MAF Tubes to begin.
well If I buy the CAI I don't want a filter with it because I will be getting a JWT pop charger... unless of course you can get that at a good deal. I can find the pop chargers for 110. The crappy Injen intake was like over 200 dollars and that thing just sucked in hot air from the radiator. Not to mention I will be moving my battery to my trunk to make room very soon.
The Fujita CAI is a one-piece cold air intake made for the 04-06 Altima and 04-06 Maxima.They are made for their MAFs compared to the 00-03 Maxima, 02-03 Altima MAFs.
Generic image of a Fujita CAI. I don't believe this one is specific to the Maxima. Just showing the basics.
If you need a guinea pig, I'm more then interested. I can find a shop pretty easily to dyno before and after. But just know that my car is modified and the results may be "inflated" compared to someone who is stock and does this modification alone.

Im interested in 3"TB , 3" MAF Tube, MAF Adapter for my 2001 Maxima
and if you do a 3" CAI count me in with the Flange on it for the pop charger

To HTPerformance: On my old car (2000) altima, I had a hotshot cold air intake. The throttle body and MAF were stock because no one made anything for that. So I put a JWT pop charger air filter on the end of it using a MAF sensor adapter and connected that with silicone hose connector. It worked very well and I was able to take out my air filter quite easily to clean it when needed.
So my idea for you would be, 3 inch throttle body into 1 piece 3 inch cold air intake with a built in flange for the MAF sensor. Then a 3 inch MAF adapter into the JWT pop charger air filter. The JWT pop charger has a built in velocity stack which definitely helps a lot.
I'd be interested in a full CAI or short ram if you decide to take it that far.
I'm also interested in the MAF tube if you decide not to go the CAI/SR intake route!

How is that working for you? What kind of performance and gas mileage are you seeing?
Great responses so far! Keep the posts coming, trying to draw out all of the possible ideas you guys are interested in, so that we can design the best product. We are currently finishing up a production run of MAF Tubes for the Ford Focus (Zetec and Duratec motors) and will be working on prototyping for the 5th gen as soon as possible.
if you made a 3'' tb the z and g guys as well as the max guys would be alll over it.
Not so sure if I agree with this. First off HP/$$ is not the strong point of a larger TB. Secondly, a few Z33's have made 300+ WHP with an unmodified TB. On top of that, there has already been a ported TB offered for the 350Z/G and has been out of production for a couple of years now due to slow sales. That combined with the inherent frugality of maxima owners makes it sound like even less of a worthwhile endeavor. It might work out, but I think it would SERIOUSLY behoove HTPerformance to do some thorough market research and not take a few users' word for it (you'll see WILD interest initially, and then...). I do applaud the willingness to bring new things to the table though regardless of what happens.
With that said, I'd be interested in one depending on the price. I would just want the project to be mutually beneficial at the same time.

Generally the benefits of increasing the diameter of the throttle body on a STOCK engine is throttle response, which translates to low end torque.
Pricing is always a question, and it really won't be known until we make a prototype to see what happens and assess the cost of making them in a larger quantity.
I had my TB bored by proflow to 70mm, it was all about the throttle response, no real gains except on the low end side of things. For some very strange reason when my engine is cold started and I tap the throttle the car stalls for a split second before reving, this only happened after I did the TB boring. I have my AFC set at 1 IN 17 OUT. I lost my damn run files with laptop hard drive crash
This whole setup is very interesting, hopefully this will all be out by the time my custom IM is done with the new cammed DEK engine, it would pair nicely with a pathy TB.

I have the dimensions for the MAF screw holes and sensor hole at work. I just finished my custom design (12" long short ram intake with built in MAF, 80mm inside diameter with velocity stack) so I will try to bring the sketch home and post the hole locations.

^You won't need that if you have your intake coupled with a JWT pop charger air filter. They already come with a billet aluminum velocity stack which is why the JWT pop charger costs so much. Good link though
I thought our stock 5.5 gen MAF inside diameter was 3.0"? What benefit of your design? I see the MAF is longer and no adapter needed...any hp gain...It will definitely conduct more heat than the OEM...what your take and outlook?
I've felt what the Fujita CAI does for the 04-06 (05-06 Altima) and I'd like some of that, haha!
