I'm going to be attempting to remove the snorkel from my intake today, but I have a few questions before I attempt anything. BlueC is supposed to be helping me over the phone eventually, but I want to clear a few things up first.



What is that box circled in red? What does it do?



As you can see in this picture, it's connected by one tube to the resonator. It's also bolted to the snorkel for support, in 2 different places. If I remove the snorkel, how will this be supported then? Can I remove it? If I remove it, how do I plug up the hole in the resonator where it's attached by the tube?

Also in the second picture, take a look at the LOWER red circle. There's two tubes running off the snorkel...one to the airbox and the one I have circled. Where does this other one go? It runs underneath the battery tray, I know that much. It looks like it ends in yet another airbox underneath the battery tray. How do I remove this? Will it affect the stability of the battery tray?

Finally when I remove the tube going from the resonator to the airbox, can I leave that hole open? It's in a place where I don't think any water is going to get to it. BlueC hasn't been too clear on this, and I haven't had a chance to talk to him yet. Also, where is the air temp. sensor located on there? He said it's plugged into a part of the tubing I'm going to be removing, but can't tell me where, just that I'd "find it."

Thanks in advance guys, this is all pretty confusing. It seems like some 4th gens I've seen don't even have that extra air box I circled in the first picture. So it just confuses me even more

 

Nevermind, I figured it out on my own when I started taking stuff apart. I guess I must have a really early build of '95 or something, because I have that box instead of the air temp. sensor like everybody else seems to have. It's really weird

Oh well, it sounds great. Real nice, mean growl at WOT 2500+ RPM's. I sound like I have an exhaust, too...and I don't. All stock. I reccomend this for anyone who doesn't want to get rid of their stock intake, but likes the sound. I noticed no loss of low end torque whatsoever.

 

hmm interesting idea. taking off the snorkel....

Eh, I'd rather hack the airbox. This way i still have the snorkel to provide a somewhat cooler source of air.

 

I think it is an early build thing. I never removed that on my '98 and I took ALL of the stock intake components out.

 

thats what i did initially, take out the snorkel. THen i put it back in thinking it "rams" in some cooler air, but i didnt plug it into the airbox. its just like half on there.enough for the airbox to pull the cooler air (if there is any...) as for the resonator under the snorkel, thats plugged in half way, but it stays...
I still get that beast growl....

 

and just for the record, Im younger than you.... haha

 

Actually, the snorkel is more of a bottleneck than it is useful for providing colder air. Take a look at the scoop, it's an extremely small opening. A lot of the air that's forced in doesn't even go to the airbox, either. I've done a couple high speed WOT runs and haven't noticed any loss or gain of power, really. But it sounds so much nicer and cleans up the engine bay. Also, this way, you can return to stock if you want to. You'd have to get a whole new air box if you ever wanted to return to stock with a hacked one.

It must be. Everybody I've talked to doesn't have it

Whatever works for you. I'd prefer to have it out to clean up the look of the engine bay though.

I believe you. I've had that status title since I was 14, when I most def. was the youngest member. But I haven't re-donated since then, and it was part of a special deal, so I can't change it. Once I get around to donating again, it won't say that anymore.

 

I beg to differ. I think the Nerds at Nissan knew what they were doing when they designed the snorkel. I think it sucks up plenty, IMO.

How can air that is sucked up by the snorkel NOT go into the airbox? It has no place to go but INTO the airbox.

 

I agree that the Nissan R&D people knew what they were doing when it came to the intake, that's why mine is staying stock with the exception of removing the snorkel. I'm pretty sure the snorkel system has no real benefit other than quieting down the intake. I'm pretty sure that's all it was designed for. In which case, the Nissan guys knew what they were doing 100%. However, I don't want a quiet intake...so I remove it. Doesn't mean they were wrong, they just wanted things quiet.

How can it not go into the airbox? Well I suppose all of it eventually has to make it's way to the airbox, but as far as air that has any "force" to it from the snorkel, half of it goes down another tube into an airbox under the battery tray...where it sits and goes nowhere.

 

The snorkel does indeed help push air in.

I did some testing last night. At low speeds I could pull as much at 2 inches of vaccum. At high speeds I could never pull more than .5 inch of vaccum.

I took readings from the resonator assembly behind the MAF sensor.

I also took readings at the very inlet of the snorkel with similar results, but could only pull 1.75-1.8 inches of vaccum. This would indicate my stock paper filter creates very little restriction.

So there...take all of your HAIs and CAIs and shuve 'em..
