I attempted to make a better intake for Vg33

[fueler]

And i failed horribly! Drank a little too much alcohol, next thing I know I have the airbox pulled out and me and a friend are drilling large holes in the front, Only the next day do I realize that the Qx4 already has a cold air intake, stock, i simply didnt see it hiding in the bumper!!! My drilling holes probably ruined the effect and is now sucking hot air in!! But there is a weird design - the cold air induction leads to the air filter box but is not connected 100%. Theres actually over an inch gap between the two. My guess is that this is for water reasons - if they sealed the two together, water would be easy to suck in when crossing rivers. With this Nissan design, you would have to get water up to the headlights before any chance of hydrolock.... If you guys were to remove the drivers side foglight, you will see a forward facing intake tube behind there. I am now considering removing that foglight! anybody done anything creative with the stock airbox?

Haha! I love when alcohol and monkeywrenching mix. Always good times.

I've thought about running a bigger pipe that sits next to a foglight on the bumper to give it a little "ram air" effect and give it good cold air.

Though I'd want to attach a valve somewhere in case of water. I'd rather it have to pull hot engine air than water. Not sure where to get that valve though. I know they're out there.

I have the vq35 (2002). The air box is large and sits on top if the squarish snorkel tube. The snorkel has much restriction.air can come up fender with some small cuts in black plastic cover on bumper and if you of course get rid of snorkel.

All sorts of dust and water will too! and this direct injection of crap is not so good. There are ways around that though. Pressure washed the inlet cover and spray went all the way up the fender right on the filter!

I made a deflector for water, shield. JWT filter. Made a big difference actually. Shocked me. You have to remount temp sensor.

Don't know if your truck is like that. But I would never go in extreme Baja dust with that system. Hard to beat stock intake for offroad as you know Fueler.

Usually!

I was thinking the same thing. The open foglight would be a good idea for street. But now I also realize how important the plastic fender liners are (mine are chopped up) allowing dirt thrown up by the wheel, straight into the intake. Did you remove your lower "snorkel" ? If so, notice any gains/loss?

[Issac]

Yes thats the real loss there. The thing goes way up into the fender, and while it might get cold air, the twist, turns and water drainage ports are odd and big.

I found with the tons of dust that the low entry point was dangerous for intake dust. So I did some funky stuff. I put a simple redirection at the airbox/snorkel junction location. Again I don't have either box or snorkel, and I noticed much dust coming up thru. So I redirected, to be more like positive air flow rather than right at the filter element.

I then did some funky stuff which was a metal surround for heat and keeping air seperated around filter. And even coat the inside of the metal surround with oil. It is like a metal k&N i suppose. Funny but it gets all kinds of dust, I wipe and oil with a paper towel every couple weeks when I check oil. Seems goofy, but if it grabs deflected dust, less into filter, and takes 10 seconds.

A better way would be a simple foam Pre filter, like the Shop Vacs use. located at deflector which is right at the opening under box.

This would flow real well. But I just found this works and while it is not pretty, it works very well. The Jim Wolfe filter does not gum up my flow sensor, and I couldn't believe it when I put that whole system in, I knew for sure it did help. I didn't need a dyno.

I was thinking about the sensor for air temp and it might be possible to play with mixture via this and location (reading), but that is a little much for me.

im going to build my own box with the intake i just put on. the hot air really gets to it. but it sounds nice. were you looking at G.A.B. (ghetto air box) mod from the maxima?

no mine looks more like this, only double the holes

[pathfinder_se_black]

hahaha i did that to my old 4runner. it was a 95 and it is the slowest car i have ever had.
