i was looking at a buddies new intake today and realized there is really nothing to it. just a filter on the end of some plpastic basically. now every1 knows the stock airflow is a joke. i was wondering if it was as easy as getting some pvc and a K&N filter and riggin me up one?

 

Check my gallery for my homemade intake.

 

thanks atelope. so u just replaced a section of ur plastic pipe with a peice of tile? that would prolly work really well if i just drove on the road but i litterally beat the hell outa my truck. i take it plpaces it should never be so i would think atleast in my case that it would allow moisture into the air intake and really mess things up, correct me if im wrong tho. on another note tho, that zoodad mod u have, now is that just to allow air to flow better to the tiny hole in our air intake? thats interesting

 

Why do you say that stock airflow is a joke?? That "tiny" hole will flow more than enough air for the V10 at WOT & 5500rpm.

 

Wow, I must be getting tired. When I read the title of the thread, I thought he was going to build an intake manifold.

 

The bigger end is just coregated drain pipe with the housing cut to fit the pipe size. I don't see it letting in any more moisture than a stock peice if you don't do the zoodad mod.

 

If I hadn't just installed a CAI kit, I'd tend to agree with you.

However, the stock intake tube has a HUGE diameter just after the MAF housing, which is a much smaller inside diameter. The effect is to slow down the intake flow a lot, and then it slams into a sharp bend.

The CAI kit I just installed is the same inside diameter as the MAF to start out, and slowly changes shape to match the throttle body.

Difference is a decent amount of mid-range torque increase, and some get-up-and-go at WOT. Seat-of-the-pants, but definitely there. I can spin the wheels (285/75R16) just standing on the gas now, and when it goes from 1st to 2nd, I actually get some slight wheel spin depending on how slick the asphalt is. AND, in the rain, that 1st to 2nd shift is now a scary event at WOT even with my cap on the back which usually kept it from slipping those tires on the exact same roads.

Of course, I have headers and the eBay y-pipe now, so the intake upgrade might not be so noticeable on a completely stock motor, but that sharp bend and the diameter difference right after the MAF is sure to make some difference even on a stock motor.

 

What intake did you install Krewat?

 

I was waiting for the tech article to come out before announcing it, but I put in a Volant CAI. Not so much for the intake temps, but the intake tubing is a much better flowing setup.

I can say, that it does make a bit of intake noise, but when it does, it's a kick in the pants. As in, when it makes noise, I notice quite a bit more torque over the stock setup. And WOT power is a bit better too... like I said, I can now spin the tires off the line, not much, but it's a definite improvement over the stock setup which wouldn't do it at all with the 285's and 3.73's. And it's all I changed before and after.

Again, I have headers and ebay y-pipe, neither of which woke it up this much. But they are sure to have helped the new intake make more power. Very happy.

Side note, I used my Autotap to check intake temps, and they are at ambient now when driving, where before it was slightly above ambient by 5 degrees or more. Nothing big, but ... it's there. Or seems to be. The big advantage was the intake tubing bend right after the air box, and the diameter difference making the intake charge slow down.

 

Look forward to reading the article and any pics of the setup.

In a past issue of Ford Performance Trucks Magazine they had an article on and exhuast, intake and SCT tuner they were dyno tuning step by step to see what increases were per mod. The truck was a 4.6l F-150 w/AOD they got a 5rwtq increase on the dyno by just removing the intake snorkel on the airbox inlet. After reading the article I went and pulled the snorkel on our 03' Explorer and the intake noise increased quite a bit, of course 5lb ft is awful hard to feel.

Heres some pics I took recently of my K&N intake for those interested.

OK, I have a question. By removing the snorkel on the airbox inlet, are we not pulling in underhood hot air instead of outside cool air? I admit I would like to do something with the snorkel of the X, but I just have to figure out what. Thanks...

 

The snorkel at least on most models is pretty worthless and is there to kill noise. The snorkel butts up tight against the steel on most models and theres just a little hole feeding the intake with the snorkle in place. With the snorkel removed air can still come through the hole. I doubt you'll notice an increase in intake temp unless you do a lot of idling with no air movement. Hot air rises and when moving the incoming air will push the heat back. I get a kick out of many "Cold Air Kits" out there that take the air below the valance under the bumper. You might as well stick the filter against the engine block because the inlet is right next to 130 deg black top in the summer time. Or the intakes that shove the filter in the bumper or wheelwell between the hot brakes, tires blacktop and etc.

 

I don't know, the rubber "snorkel" (if you want to call it that) didn't butt up against anything, it was protected from water ingestion by the radiator support.

My stock air box has two holes in the bottom of the box - sucking in engine compartment air. So...

 

Interesting... Would the Volant air tube be compatible with stock airbox and filter?
I ask this assuming Volant is using some kind of K&N type gauze psuedo-filter. I am not a big fan of those as as I run my vehicles for several hundred thousand miles before discarding - and our dust out here is granite based and quite abrasive.

 

Unless Art has a new Volant model, the CAI for our trucks has been out for a long time. They can be seen at Volant's website with pics. I tried one and it didn't fit, even told by Volant Tech Support how to modify it. For the $$ I wasn't going to modify it. Now another member here recently put one on with only minor difficulty, Art's might have bolted right up. Seems different years create different problems. After my front snorkle mod, the only problem I see now is the factory looking "bellow" right before the throttle body.
