new intakes are being tested for the 3.5 Maximas currently and will hopefully be released the first of next month. this intake is a 100% complete replacement for the OE tract and boasts a design all it's own.

what air filter is that in the pic for the intake???

 

oooooooh that looks tastey!

 

ooooh oooh can i test one out for you?

 

Yikes! Expensive for a midpipe and filter........

 

when i saw the price i was like

but i still wanna know what filter that is

 

Now with that design...there is no flex tube...so could that make the MAF more likely to fail?....i dont know if the vibration can make it liable to fail faster.

 

we are currently testing the product out through a considerable amount of abuse and timeframe to assure that it will be a very reliable product. vibration should not be an issue.

as for price, it seems relatively expensive as compared to the others, but we are using nothing but 6061 billet aluminum in the T6 condition and have more machining and welding processes that go along with the MAF sensor tube and flange. it also comes with all new hardware at the highest quality. and is the only 100% complete replacement intake.

the filter is made by Tsudo Japan. it is a dual velocity stack dry element filter so it will not interfere with your MAF sensor.

Chinaonnitrous1, if you are in the area and would like to test out another new product, lemme know.

 

I wonder how you guys mount the intake onto the car? similar to Stillen/JWT/Berk or using a bracket like franken car? people suspected that blown MAF is due to excess vibration to the MAF when the intake is not properly secure.

 

one more question....will you guys develop an intake for 2k-2k1 maxima?

 

Do you guys incorporate a screen before the MAFS (like the stock design)?

 

looks like the Franken intake to me....

 

not completely....it has an adapter for MAF sensor on the midpipe...so you dun have to use stock MAF tube.

 

You guys are forgetting the one of the most important things about this intake , it is made out of 6061 billet aluminum in the T6 condition, that will never rust and is a higher quality.

 

we got more to worried about than rusting midpipe.

 

nice

i like to know when i can order one?

 

you will be able to place an order as soon as we complete testing and are pleased with the results and no complications arise. our expected date is August 1st, however i will post another thread the day before they become available.

we do not incorporate a screen as it hinders airflow and is not necessary as the openings in the screen are nearly 1/8". there should not be a thing that the screen should catch that the OE filter could'nt. if there is enough demand, we will offer it as an option to those who truly desire it.

'00-'01 applications will be produced if there seems to be adequate demand. if so, expexct the earliest release to be during the winter.

 

2xF, I live 1-hour away from Toms River, NJ & would consider being a test-monkey!... Email me with the details. I have a 2k2 Auto GLE maxima.

Thanks,
G

 

Oh well...im out here in california. If you would like a california guiena pig complete with dyno results..Just let me know

 

I knew that That's why I offered to help him... cause I am an O-K guy!

My intakes use T6-6061 Polished aluminum and 304 stainless steel. I like your design though. I was going to incorporate the sensor adaptor into the mid pipe like that as well but I was worried about debris and excessive vibration.

 

That looks like the Blitz filter .

 

I'm a little concerned about doing business with an intake manufacturer who has decided to remove a part from the intake track the function of which they obviously do not understand. Perhaps a lesson in MAF technology is in order:

http://www.greghome.com/Greg's%20Gar...FSensorMod.htm

You may choose to argue Greg's point, DoubleF. But there is no escaping the fact that you did not know the actual purpose of the MAF screen. That fact may not bother others. But if I were considering the purchase of your intake, it would certainly bother me.

For those with 2K2 Maximas, I would STRONGLY recommend against purchasing an intake that removes the MAF screen, particularly given the frequency with which Nissan MAF sensors tend to fail.

Caveat emptor!

 

I agree y2kse. I was looking at the pics of it on their website and I dont see how it is different than a frankencar in any way (with the exception of being shinier and more expensive).

 

I believe the Frankencar intake utilizes the OEM MAF assembly. If that's the case, then the MAF screen is retained. In DoubleF's setup, the OEM MAF assembly is eliminated along with the MAF screen.

 

Ok. Just do us all a favor, let them test it , if it works, let others buy it. I for one am not interested, but other might look at it as something they may want to try.

 

My position is the same as always, kloogy. What people do to their cars is none of my business. All I'm interested in doing is presenting the facts. And that's precisely what I've done.

Frankly, I don't care whether DoubleF's intake works or not. My concern hasn't got anything to do with that. It's based on the fact that he doesn't seem to understand intake technology. Now some potential purchasers may be willing to buy parts from a manufacturer who doesn't understand the technology behind the products they sell. But I, for one, am not.

I believe it would be useful if DoubleF explained his obvious lack of knowledge concerning the purpose and function of MAF screens. Perhaps his explanation will alleviate my concerns. And then again, perhaps not. Alternatively, DoubleF can exit gracefully by simply agreeing to put MAF screens in all his intakes. At that point I'd be willing to drop the issue entirely.

 

y2k, you are in fact correct in saying that the screen is for accurate readings for the sensor. but you're "lesson in intake technology" did not enlighten me to anything. all i saw was that two MAF sensor assemblies from a 4th gen with and without a screen were compared and nothing was found. am i correct in saying that? i understand completely why it is there. most people understand the screen to be a secondary filter and answered it as such. do you know why a screen is really needed? it is because air follows the same laws of physics as a liqiud with a specific gravity of 1. this means more air will flow along the surface than in the middle of a tube. the screen will "grate" the incoming air to bring air from the edges in and evenly distribute it across the diameter of the tube before the sensor. thereby allowing the sensor to more accurately gauge the incoming air. it does not straighten air. after the air has passed throught the screen, it will tend to follow the edge granted the path is free of turbulence. this does hinder airflow because it introduces turbulence into the airstream and IS proven on the flowbench. that is why only one is placed in font of the MAF sensor. if all it does is straighten the air, why is'nt the whole tract screened as such for zero turbulence? if somebody would like screens for peace of mind, i'm here to work with that somebody. my mission is to help those find performance parts that are unique and cater to the consumer.

 

Thanks for responding, DoubleF. There's quite a bit of controversy about removing the MAF screen. Anyone who wants to research the subject can do a Yahoo search under "MAF Screen".

My chief concern is the fragility of the Nissan MAF sensor. If you take the time to do a search on "MAF Sensor" in this forum, you'll find a great deal of information on the subject.

I have no idea whether relocating the MAF sensor pursuant to your design and removing the MAF screen will contribute in any way to the problem of MAF sensor failure. But if experience can be used as a guide, people who purchase your intake WILL EXPERIENCE MAF SENSOR FAILURES! Obviously, it would behoove you as a business person to keep to a minimum the number of possible factors for such failures that may be caused by your design.

There appears to be NO PERFORMANCE ADVANTAGE in removing the MAF screen in a 5th Gen Nissan Maxima. As a result, I encourage you to install one in every intake you sell. If someone wants you to remove it, let that be the option instead. Otherwise it's only a matter of time before purchasers who experience MAF sensor failures with your intake point to the lack of a MAF screen as the cause of the problem.

 

To summarize your situation: You will sell more intakes if you retain the MAF screen. You have a certain percentage of the market that is actually well-informed enough that they will NOT buy your intake due to the elimination of the screen. The uninformed consumers will buy whatever you put out. It's probably worth your time to re-engineer the tube to add a pre-MAF screen so that you gain the additional market of discriminating buyers, wouldn't you say?

 

Guys I have been running around with this setup for a few days already. The MAF screen would be a good idea to have for warranty or piece of mind purposes. I seriously doubt it's there for anything other than extra filtration. The only other concern I have is that the inner diameter of the tube is near identical to the the oem part which is about 70mm. If this product uses 3" OD tubing with .062" sidewall then all should be fine.



Sometimes the car appears to be a little faster and sometimes not. My setup leaned out my fuel mixture because I used a larger MAF tract which I have to compensate with extra fuel pressure. I'll probably be putting the stock MAF back on today seeing as how this was only an experiment anyways.


As for the said product, I think it's a great idea to somewhat do away with extra fittings and install the MAF probe into a different unit. But I can see that some people are going to have some problems with it.

 

SR20DEN, I sent you an Email reagrding your intake. I'm willing to donate parts for your cause. You are putting your work into making Maxima's faster and better, I want to contribute.
