I have the Volant CAI & Snorkel installed in separate occasions. If you liked the Volant CAI, you will love it with the snorkel.
I have the same feedback as yours, but with the snorkel, it's even better.

I installed my Scan Gauge after installing my Volant CAI. The Volant CAI still sucks hot air from under the hood as a divider to block engine heat from the intake is not included in the kit (but can be easily made) and the intake in still under the hood.

The outside air temp in where I live is constantly 90-deg during the day. With the Volant CAI, start-up temp, as shown on Scan Gauge's IAT reading, shows on average 135-deg. and warmed-up engine is usually around 180-deg. With the snorkel, start-up temp is at 90-deg. with warmed-up temp average at 120-deg.

Just posting this as a contribution for everyone's reference based on my experience.
thanks for the temp #'s. I haven't read this whole thread but I will relate my experiance with the stock air box and some properly placed hood vents on my 06 LJ Rubi. I have had the vents on my jeep for the last 18 months but have only recently installed the scan gauge. I have noticed that my IAT are about 5-10 degrees higher than outside air temps at highway speeds (50 plus). I am comparing the IAT on my scan guage to the air temps on my mirror. when I stop or am traveling slow they rise much higher; around 20-40 degrees higher. my findings have been pretty consistent from 30 degrees up to near 80 degrees. my start up temps have been typically just under or at outside temps (when cold) to very near outside temps (when warmer). from what I have seen anyone looking for a CAI will probably benefit more from some hood vents then they ever will from a CAI.

k and n are fine so long as your not in very dusty or muddy conditions or submerging your jeep in pools of muddy water but then again why have a jeep for any other reason.

Cai

Ok guys, I am looking to get a jeep soon. My current car is a 2003 hyundai tiburon GT with some mods done to it, but I have no room in the thing. It is one of the smallest 2 door coupes you could ever fit in. That and the fact that the trunk is filled up with 2 12" inch sony xplod subs.

But enough with the rambling, cold air intakes are very useful. For one, they do add a slight horsepower gain, obviously you will notice the gain more on a sports car than a jeep. And you don't have to worry about hydrolock unless your driving through a river. My car is barely off the ground(1-2 feet) and I drive with my cai in ANY type of condition. Now the cai pulls out cold air to the engine from the bottom. The air gets sucked in pretty close to where your left front tire would be. This makes it away from the engine compartment so it doesn't suck in hot air instead.

And yes, I think the whistling sound it makes and the swooosshh! sound it makes when sucking in sounds great. It's like a cargasm! lol.

I know this is a jeep forum, but here is a little vid of what my cold air intake sounds on my car:
Note: please disregard the exhaust sound in the background.

You can't compare a ricer Tiburon with a Jeep 4.0L. Completely different purpose, different technology, different environments, different engine, different EVERYTHING. Go back to the first post and read the entire thread. You don't have a Jeep and you don't understand how they work, so don't add misleading information for the people who actually want to use this forum for a useful purpose.

most CAI's don't relocate the filter, they still sit more or less in the same place, and there's a metal fender well there, so almost no "cold" air is coming in from there.
secondly, the air tube of a 4.0L jeep nor the filter, nor that little horn thing on the stock air box is restricting air flow in normal driving. check the graphs to see what RPM's the mfg's show gains at...it's always above 3000RPM. i don't even accelerate above 3000 unless i'm on the interstate.

what you should take away from this is... several ppl have used scientific measuring devices in real world scenarios to prove that a CAI is almost the biggest waste of money for the 4.0L.

X2. In a TJ, a CAI is pretty useless. It doesn't get enough cold air to matter and on a TJ, which isn't a racer, even if it worked it'd be like adding furry dice to the mirror... just not something many people driving Jeeps would care about... those under 20 excepted. ;) :2thumbsup:

One thing I like about a high flow filter, is the increased throtle response, instead of the delay. My brother has a CAI on his 2000 TJ, and I have the stock air box on my 05 Rubi, and the throttle response sucks on mine. I dont race nor do I hot rod but the delay when you give it gas is so annoying and doesnt feel like a normal vehicle like my brothers does when you accelerate.

Since the OE air filter and intake isn't restricting the air flow in any way, it really does not, that's simply a good example of the placebo effect in action. :)
I can prove that there is less delay. I took off my box one day and got the cone off my brothers and clamped it on my stock tube. There was no delay when I accelerated or took off from a stop. This is not placebo, because its night and day, Im not bragging on increased horsepower and torque and how much faster it is, Im simply saying I know there is no longer a delay. Dynos measure hp and torque, its not something I can do, but when I feel there is no delay any more. Im not that big of a fan of the costly CAI, but I gotta give credit where credit is due. Have you ever used a CAI on your Jeep Jerry? Even if you have you probably forgot how it felt. Stick someones cone filter on your stock air box one day and I garuntee you you will feel better throttle response.

stick your hand down your throttle body and see how black it turns. i'd like to keep my engine clean. the need for a snappy throttle in a jeep is kind of like putting a parachute on a postal truck...

jerry, do you know anything about true-flow filters? paper is not an option for me as i don't have room for the stock box anymore. I know traditional cotton/gauze filters suck, but not sure about the sponge style of the true-flow. (read that as, did i waste my money buying a true-flow filter, would a pre-filter be a good idea?)

Dippert, the TrueFlow air filter seems to be a pretty good one. I dumped my K&N with two prefilters over the top of it in favor of the TrueFlow and it seems to be filtering pretty well. I put both of my prefilters over the top of the TrueFlow rather than trash them, I believe my engine is finally getting some clean air. I didn't notice (nor did I expect) any throttle response difference. :)

good to hear :2thumbsup:. i didn't notice a difference in the engine either.

The reason it will turn black is because of carbon, not from inadequite filtration.

Im not saying I want a snappy throttle, Im saying I want a normal throttle. Im tired of giving it gas in the rocks or in the mud, and having a delay, it might not be something you want but its something I want.

Not trying to "stir it" with this post, just presenting more information for everyone to look at. Hopefully this will help someone.
I will NEVER use a test by the maker of the item being tested for the true information...never. Useless, shouldn't even bother...

Also on a side note:
I use a True Flow filter with a K&N FIPK cai, just so it is known what/where with me.

True flow says NOT to use a pre filter. Don't know why, but I called them and was told "no pre filter".

Then maybe you just need to replace your filter?:confused:
