Well, I have looked around for an air intake for my VQ35. I really like the CP-E for the Altima, but they want $500. On eBay I can find OBX ones, but I am not sure if they need to utilize the original MAF housing or if the MAF/AIT sensor is bolted in, and seller feedback is low. Another choice I have found is a cheap MAF adapter with crappy looking filter. Is that a decent option? Cheap MAF adapter with a K&N cone filter?

I could not find the other brands of WAI that the 5.5 gen guys use. I don't want CAI, I want to keep the cost low. Any suggestions?

Can I use Altima WAI for the VQ35 from eBay?

 

most people just use any 3.0 intake pipe with a adaptor and filter.. thats what i have.

 

I think because I am using the full swap, e-gas throttle body and A33B MAF I need an A33B specific WAI setup. The MAF from the A33B has a different size and hole pattern than the A32 setup.

 

Or:




Depending on what level of sound you are interested in.

 

For the first picture which looks to me like the "silencer" portion of the stocker plus the intake duct is removed, how much of a difference is there on this setup compared to the 2nd setup pictured in terms of both power/response and sound?

1st set-up is my favorite with respect to sound/smoothness etc.

The 2nd one is dyno proven but very loud.

But, keep in mind, I have not dyno'd the first one yet.

 

Thanks for the quick reply, I have been looking to change my intake but was curious if just removing the silencer was worth it or not? I'll have to take a 2nd look when it is light outside but did you just use a silicone coupler to take up the space of where the silencer was?

 

I'm using a different MAF housing, so I couldn't physically fit the resonator with the new sensor housing.

That's a coupler from Lowe's. 3.5" ID.

 

thanks

 

This is my current setup:


I'm not trying to get WAI benefits as much as I need a suitable intake that fits my A32 a bit better. I was "hoping" that there would be a better selection of WAI parts, but as I have seen in this thread and others people are making do with parts they come up with. The A33B airbox doesn't fit quite right in my A32, but I may still just try and live with it for a while.

 

Does it rub? Are there clearance/fitment issues? The picture doesn't really point to any real 'problems'. Can you not fir the snorkel in there?

 

Well, I had to pull off the upper metal frame, and none of the bolt holes have anything to line up to. I am not sure the snorkel will draw in air after I close the hood, so I have left it off for now until I can pay more attention to it.

Also, the airbox does not line up too well with the strut tower and fender well, in that pic it looks OK, but looking down on it it's obviously not made for this car.

 

The snorkel should fit ok, since the A32 snorkel is very similar in dimensions.
My airbox isn't secured down by any bolts either.

 

Exactly how much power we talking...care to post a dyno graph please???

Nice...I might do this and get rid of my Injen so I can have some more $$$ towards some Cattman headers.

 

good luck getting much money from an injen, most member have realized that they are not beneficial.

as for the intake, i like mine a lot. which is this: filter<maf tube<hemholtz resonator<coupler to IM. like nmex said, with a cone filter on there its pretty loud, but it sounds really mean and as long as i dont spend a lot of time at WOT then you dont hear it. also, someone did a dyno comparo of a number of intake designs.

Edit: two people did, and here are the threads.

where are your vacuum tubes?

 

The A33B doesn't use any vacuum tubes like previous generations. This is because it does not use an IACV. It only has 1 connection, and that's for the PCV. And mine is obviously eliminated (small filter on the end of the VC PCV port).

 

no fair

 

That was always a 'drawback/sticking point' whenever modding my 4th gen intake tract(which is the same as yours).

You're going ms, so, I would say that's one of lesser obstacles for you right now.

 

with the PCV not taking air in, would that make a big enough difference in flow that the computer would notice and you get slightly advanced timing as a result? not sure how much air a pcv line requires.

 

It idles lean/rough w/ stock MAF housing. Nearly turns off with an 82mm MAF housing.

Idle timing is the same though. WOT timing seems to be the same as well (stock MAFH vs LRMAFH)

 

my intake has 3 hoses coming out of it... the big one is connected to the top of my front valve cover, one of the small tubes seems like it connects to the vias and map sensor, the other small tupe connects to some metal tube that I have no idea what it does... I dont think there is an intake tube coming from my pcv valve... i think i heard that the vias does not need vacuum so maybe i can disconnect that tube... but the other two i dont know about

 

Just do a GAB.

 

Never said anything about a PCV VALVE.

The one coming out of the valve cover is the PCV. PVC = Positive Crankcase Ventilation.

 

I was thinking of trying this setup at one time with stock Maf, but what I ran into was that the MAF plug was not long enough to reach that far. Can you just peel back the wiring harness and pull out more wire?

 

yes

10char

 

Also there isn't any problem with not using the vacuum hose and just using a crankcase breather filter is there. I mean I thought that the intake pulled a suction on the hose and if you replace that with a filter it could breath but there wouldn't be a vacuum, right?

 

Refer to the first sentence^^^^^^ http://forums.maxima.org/showpost.ph...0&postcount=23

 

This doesn't answer my question in the slightest...

 

yeah i agree, unless that is a A33B issue i have a breather instead of that pcv tube and my car idles smooth... I can speak for the leanness though cause I have no way to monitor that

 

Is this a question? If so. There is no problem aside from idling lean. It's not really a problem, but an observation. it does idle a little rougher due to it not being there either.

I do not understand the question. Read the PCV portion of the FSM.

What EXACTLY do you fellas want to know?

 

Thanks, you were right. The snorkel fit perfectly, but the airbox still is not bolted to the car.
