Very nice!

I'd want to put some sort of mesh screen over the hole and fake the same on the opposite side just for some aesthetic balance. Step 2!

You need heat shielding around the filter or it will use hot air.

I tried this out with a plastic piece of flex tubing from the ricer section of my local automotive store. Took about 20min from start to finish and I can actually feel it pulling in air when I put my hand on the grille. This is a great mod for the pathfinder guys b/c that grille by the foglight is so perfectly located. Pic from inside the stock airbox...

Yes you have to remove the original one, and I did come across a sensor (intake air temp sensor) i just left mine dangling.

yeah i was planning on doing this setup but with the stock box intact to keep the warm air out, i am actually looking for a air bypass or researching on it any ways to see if really needed, i had a car before that i did the same thing to,without air bypass, with no problem, but just being extra caution

you gotta jack the car up, its easier if you take off the wheel but i didnt do that

the air intake is 2 parts - upper air box (with filter) and then theres a lower part (resonater?)

the take out the lower part, like i said jack the car up, and you have to go through the drivers side fender lining. its just a few screws and clips. then the lower part is held in with about 3 10mm bolts. if i remember correctly.

Thats a pretty cool mod there. I was lookin at thishttps://www.4x4parts.com/catal...=3367 on 4x4parts a lil while ago, but I think I'd have to cut my intake pipe about 2 or 3'' to fit the ram air to the cold air shield on the filter. My Weapon R CAI came with the heat shield, but I think the intake is louder without it on the cone, and I don't think it actually keeps heat off the filter.

Theres an actual picture of my intake, I ordered it from Weapon R directly, and heres the picture on the site. 96-00 Pathfinder:

And thats not what I was sent, false advertising... Anywho when installing my intake first off I had to cut off about 2'' of the intake pipe on the throttle body end, at an angle cause the angle was all off (the filter would have been through my headlight...) Also it came with a converter for the MAF that was too big, they sent 3 cupplings, 1 for throttle body, one to attatch intake pipe to MAF, and the last one which was 3'' at one end and 2'' at the other, which was usless... And the tubing wasn't long enough to go from point a to b, so I had to get some from a friend.

Enough bickering out of me, I just thought I'd share my intresting Intake story. ANd dont ask why I have three posts instead of one, I guess its for street cred...

Seems like were off this subject now.. But anyway I also did the mod, but I connected the pipe straight to my filter. The outcome wasn't impressive, less power and quieter intake...



Also I ziptied it to the old airbox bracket so I wouldn't have to mess with the foglight cover.

that is nice

was there no increase because the intake was no good or did it get worse when you installed the pipe to the fog area?

i was thinking of doing something like that but i have a K&N and it came with everything and was easy to install.

look at that nice bend that you have in your intake, obstruction of air flow and for roger i would just leave the k&n and run the hose to get some nice cool air there

Once I connected the pipe to the intake filter my 0-80 was like probably 4-5 seconds slower, and I dont think the bend in the pipe makes a lick of difference, cause I held my hand up to the pipe, and like jcpathy said my hand would just get sucked against it.

I don't know if this is just a better highway mod, but the direct connect wasn't good for me. And I know my intake can be herd from about 3/4 of a mile away and I didn't wanna change that

it looks like weapon r made some sort of weird filter cover that, in my opinion, looks kinda restrictive....

It's supposed to act as a heatshield, but I don't think it does anything but quiet down the intake. Thats why I don't have it on, it's great for goin through rivers and stuff though keeps most the water out.

I just cleaned my filter with some cleaning solution weapon-r sent me, rinsed about a cups worth of black and brown stuff and some dirt particles. Haven't cleaned it since I threw it on a year ago, I guess I'll find out later if it makes a difference.

fueler,I realize this is old but thanks for posting. I recently removed it and the Spectre intake I put together and installed the stock airbox etc trying to eliminate some issues. Anyway, I plan on putting the aftermarket intake back on in the spring and doing this mod. Do u know if the Jimbo Wolf bracket worked for you. I remember not being able to get the bracket in a decent spot and making a new one.

Also, I am looking at ReKleiner's install and was thinking if there was a wider square attatchment on the end of the hose behind the fog light cover, should force more air. I remember an aftermarket "ram air" intake like that made for the old Impala SS's. It was like a big rectangle that would fit in a cut in the bumper valance attatched to a hose going directly to the air box I believe

i did this mod a little over a year ago. i used 4" gutter tubing with the square fixture for the ends of the gutter. the square piece fit really nice in the grill area next to the fog light. i just cut the vertical plactic pieces out so that i kept a stock look. on the highway it helps with the power...but fuel mileage is worse. especially in the cold.

Thanks for the info fast--I believe I have what you are talking about--the extension is from a company called "flex-a-spout". I will look into it. Thanks for the info on winter etc as well. I have decided to keep the stock airbox on for the winter at this point, Path is driving really well after cranckshaft pulley replaced. Really lose desire to work on the vehicle in cold weather as well.

im pretty sure that is the name of the stuff. i know that it worked out really well. the 4" was big enough that pulling it through the first ring in the engine bay held it there real tight, no zip ties or anything and the square gutter spout end fit the opening well. a little bit of plastic epoxy to fix it to the grill and its done. whenever you pull the grill out it pops out of the pipe and pops right back in.

Update, with the Path out of commision until I replace calipers I figured it was a good time to try this mod. I already have the Jim Wolf intake. Removing the "resonator" is only 3 10mm bolts. I didnt have to jack up the vehicle or remove wheel although that would have made it easier to be sure. There is 1 bracket I had to loosen that helps "hold" the bumper. Had to loosen it to pull the tubing down. Havent had a chance to test out the improvement or reported gas mileage unimprovement. In theory, this looks as close to a "Ram Air" setup as possible. I am expecting at least .001 extra horses and a 1/4 mile time of at least 35-40 seconds. Only thing I am curious about is the intake temp sensor. What is it really for? I am going to zip tie/Innovazn "zap strap " it to something and hope for the best. The additional weight loss of about 19 oz of worthless plastic should net some additional gains as well. And thanks Nissan, for putting out a V6 with 171 horses! Mustangs, look out now ( I wont be as far and indistinct in the rear view mirror as previously.....)

The IAT (intake air temperature) sensor tells the engine the temperature of the air entering the intake so it knows the density of the air entering the engine. Normally you want the sensor on the intake tube or as close to the air filter as possible to get an accurate reading. If you place the sensor in a remote location and the air temperature is different than that of the air entering the engine, then the engine will run rough and will probably throw a DTC for the IAT sensor. On the 2003-2004 Pathfinders they combined the IAT and the MAF sensors into one, so I would suggest placing the IAT sensor somewhere between the MAF sensor and the throttle body on the intake tube.
