I was talking with someone else about this. It's actually a good Idea if you don't plan to do water crossings. It should keep the filter cleaner and cooler air also. I like it.
Why thank ya sir. I know some guys that do injection molding. I wonder what material would be best for this. Like an ABS?
Your not going to gain anything by this, but make the breather more easy to get water and debrie inside the air box, every mud puddle, etc. If your going to put a large hole on the side of the fender, it makes allot more sense to run the snorkel, I get about 3 degrees over ambient air intake to the engine by running the snorkel into my CAI. Sorry, but it's a bad idea IMHO.

It's ok I expect blanket statements like that. And heck, for the small amount I know you could be right. I'm sure years ago there were posts about snorkels being a bad idea too, so who knows. Besides, the snorkel surface area for the opening seems a little small, is way to long and has too many turns to be effective for this.
I do know in the models like I've seen (I'm not coming up with a new concept here, just new to the FJ), there are filters behind the scoop, in fact making it harder for debris to get into the air box.
As for no gains, I don't agree. I have a gut feeling you'd see power gains commensurate to how fast you're driving... Up to a certain point of course. Air blasting directly into the air box has to have more of an effect that randomly finding it's way in from the wheel well.
I did a lot of research on hood scoops this past week. Here's what I found:
The placement of the inlet is extremely important. This is why most cold air rams are placed under the bumper or in the front grill; its an area of high air flow around a vehicle. With the snorkel waving way up high over the truck, some air will obviously get in there, but it's so far away from the truck that it's in an area of low air resistance. That and the distance is so far away from the air box as I mentioned before.
Hood Scoops on older muscle cars were sometimes considered ineffective not only because of the placement, but also because the air filters were open to the engine bay. The air was not only hot by the time it got through the filter, but it wasn't going directly in either. Having a sealed air box seems would overcome this problem and lower temperatures while forcing more air through the system.
"If you want to further increase your Volant Cool Air Intake’s effectiveness, add on the Volant Performance Air Scoop. Customers using the Volant Cool Air Intake with the scoop report 2-4 MPG improvements in fuel economy, as well as dyno-proven horsepower and torque increases. Volant is the only air intake company to properly apply a functioning Ram-Air Scoop to a sealed air intake box. The scoops fit without any modifications and are formed to match each vehicle and attach to a high air-pressure point behind the bumper or near the vehicle’s front valance to take in nothing but cold air. The Volant Ram Air Scoops are made from the same heavy-duty, durable x-link polyethylene plastic as the intake systems and are simple to install and feature baffles &/or drain holes to prevent the injection of water into the intake. These Performance Air Scoops are a great way to upgrade your existing Volant cold air intake system (which is sold seperately) to add dramatic increases in performance as well as fuel economy! The Volant Performance Air Scoops come with a 1 year warranty." Quote from an a Voland ad I saw online.
This looks very promising. Volant makes an aftermarket air box that has an entry point for the scoop. I would think a careful mod any of our CAI boxes could yield the same results. Thoughts???
No the Taco and FJ have differnet hoods. That is a good idea with the intake being attached to the hood "faux" vent on the FJ. Actually putting it to use, but it would need a vent system to limit water into the intake. Cutting on this application would be necessary.

A lot of poor information in the above statement (which appears to be a straight advertising statement versus an original post - should quote the source). First, the FJC has a completely different hood than the Tacoma. Second, the reason Toyota (and many other companies) pulls the air in from the side of the vehicle is that it avoids using pre-heated air flowing over the front of the car, where the radiator is. And the snorkel works the same (actually, better, IMO) as the scoop, extracting the cooler, cleaner air rather than the warmer, dirtier air at the front of the vehicle at hood level. And that "scoop" would spell disaster in a deep water crossing, if you were to find yourself in that situation.

Again, this is not about "GUT" feelings. I run a Scan Gauge II, I monitored intake air "BEFORE" installing a TRD CAI. I was getting with a stock breather setup anywhere from 26 to 30 degrees over ambient air intake. I installed my CAI and ambient air dropped a min of 20-25 Degrees once I installed a CAI. I then installed a Snorkel and the intake air droped another 6 degrees in air temps, now running 3 degrees over ambient. By having the intake at a higher level, insures that the engine only recieves cold air.
PS. I'm not bashing you, I think it's great your thinking outside the box so to speak. I just want to point out, that allot of members have a lot of "REAL WORLD" info on here that helps when trying to figure out something new. Check out the tech section.

Hi guys thanks for all your input. I completely understand and respect the technical side of things and having real world numbers to back it up. Absolutely no question.
Yes, the statement above was straight from a Volant advertisement (I thought that was obvious, but anyway). They state that they have either a filter or proper drainage in place that would take care of water issues. Again not submerging the truck! I didn't realize the number of people on here that use their FJ as a submarine (I'm saying that with humor, relax). At any rate, the above product I think would be the perfect complement to the fender port.
About the snorkel- I didn't say the snorkel doesn't cool air going into the intake, so please don't infer I did. What I am saying is that a shorter more direct scoop with a larger surface area will do that more effiecently. If you need me to build one to justify my gut feeling, I just may.
And yes Air's filter layout is pretty cool and he's received a lot of praise for that. In my opinion if the cone was seaeled and only let air in from the hood vent, that would be much more effective. But he's got so much power coming from his supercharger, pulley and probably different gearing, it doesn't matter anyway.
And as for the Tacoma's I wonder how different the placement of the hood vent is. It seems it should be somewhat close to do a little modification to the tubing might not be so bad. And if you guys have time, take a look at FJoel's thread on the Volant intake from the Tacoma. You'll notice it has two ports on their aftermarket air box which makes total sense seeing that you'd get cold air coming from the fender and more air coming from the hood vent. I've read from a lot of Tacoma owners that adding an extra inlet inside the engine bay was the way to go. Its supposed to be a common mod on their stock air box as well.
I'm going to do some research during the day and see what Volant has to say about water and fitting this on an FJ.
