The intake's trumpet, as it's called, may seem restrictive but it easily flows more CFM than the engine can draw at redline and WOT. Its opening was purposely made that diameter to speed up the air velocity for more thorough combustion and a quieter air intake. That it's restrictive is a common misconception until researched more thoroughly.
But you can easily remove the trumpet with a quarter turn if you really think it's restrictive and causing you to lose street races.

The factory system is restrictive due to the air box intake snorkel having a smaller inlet diameter than the throttle body has

After a few drives with the heating and cooling you can snug them down a bit more and that should get rid of the whistle. I put intake on my jeep and love it. Now it pulls cool air and also raises where it's getting the air from. Lastly it gave me room To put that storage box in which is awesome because now i keep all the recovery equipment in there. I usually run with the doors off and that used to be an expensive gamble to keep all the snatch blocks, tow straps, d rings and tree savers in the cab.|

I have this intake as well... For justified reasons, although I dislike the shiny smudge magnet under my hood.
Mine whistles... Not a light whistle but an extremely loud almost bad pully bearing whistle. A slightly higher pitch though. Dear god its annoying.
Has anyone dealt with this issue? I can deal with, and actually enjoy the slight whistle when in that 1500-1600rpm range but lately mine is whistling any time there isn't a load on the engine. Idle - 3000 rpm.
I'd love to keep and justify this intake but I need a solution to this issue first. Otherwise it's being sold or crushed. Haha

|Majnoon||Wow. That's a big azz box! I like it. Hey performance gains will not exist but damn that box is nice. Could fit lots in that.|
|07-25-2014 09:28 PM|
I was considering this intake not for the gains but for the extra storage space. They have a box that goes in the place of the airbox that you can put stuff in. Not really sure if it would be big enough to stow anything useful in. Just looking for some decent options for extra gear since I usually have the gf in the other seat and the dog in the back (don't need everything rolling around nor do I have a lot of room with the dog in the back). Here is a link to what I'm talking about. Are there any other decent options? I was also looking into the molle attachments that bolt into the tailgate but my rear hatch leaks slightly with a lot of rain so it any gear could potentially get wet.

|jeepermcclure11||Yeah it will! Its the same O.D. on the throttle body|

|jeepermcclure11||Spectre is a good option if you get the river raider cowl snorkel!! It adds a filter to that snorkel and if you dont like the look of the Traditional snorkel river raider is sweet|

|2JeepsThatRun||Does any one know if this would fit on a 2.5l with a 4.0s throttle body?|

|IslandTJ||Meh, IMO the only reason to replace a Jeep's stock airbox is to make space for OBA. Anything else, is time and money expended.|

1. make room for a fender lift.
2. too lazy to find junk yard parts that fit.
3. another reason to play with the dyno and verify, or call BS on their claims.
4. To get fresh cowl cold air.
#4 is the best reason for a cowl intake. My IATs dropped substantially and run about 10* over ambient. This will cause a gain in hp under certain conditions that would be difficult or impossible to measure on the dyno. It really lowers the IATs while going slow offroading. I have seen IATs of 175F while the stock intake is sucking that nice fresh air off the back of the radiator.
I'm going to install a 90* elbow inside the cowl to cut down on the sound, and install one of the cab filter cowl scoop things (maybe 2 of them). Then I'll have a double filter, and the in-cab HVAC will be filtered as well.
Here is my testing data.

I bought an 04 TJ Unlim. which had one already installed. I owned a '00 sport before this. Same engine. I DO notice a difference between the acceleration of this jeep vs my other. What I'm looking for now is a way to snorkel this sucker so that I don't have to keep cleaning my air filter every time I get muddy. Something to think about though is IF it does introduce cooler air, this will definately help over the life of the engine. You add a louvered hood and you may extend the life of your engine for many miles.

|99TJCrawler||I have one of these. It will not get you better mileage.|
|03-25-2011 10:38 PM|
|s3nt3nc3d||What mixture? Our engines are fuel injected, not carbureted. The intake only allows air into the system...the air and fuel aren't mixed until they enter the cylinders. A cold-air intake on our engines will have no significant effects on fuel economy.|
|03-25-2011 09:45 PM|
|eric_b993||Does anyone know what this does for mileage? It should increase efficiency by making the mixture burn better, but does it?|

|99TJCrawler||Just installed it yesterday. I don't feel a real difference to be honest. I didn't expect a lot out of it. The throttle response seems a little snappier. The biggest benefit for me, as I stated earlier, was gaining the space where the intake box used to be. Right now, I'm working on how to turn this into a snorkel. Shouldn't be too difficult to do. Just so you know, the hole you need to drill in the firewall IS NOT in the dead center. Make sure to read the instructions. I did not read them but fortunately, I made the hole on the passenger side anyways lol. That could have been really bad. Like I said, instructions are your friend. Overall, the install was very simple. It makes it easier if you take off the hood also. Anyone know where I can get a snorkel head from w/o having to buy the kit?|

thanks six gun matt, and 99 tj crawler, i was guessing to use black silicone, please get back to us and let us know how you like it, does it make noise, etc.
thanks again, i live vicariously through you until i can do this to mine. (still at engine shop in pieces) week 4 now

|99TJCrawler||Holy crap! That is awesome! Your going to put a freaking welder where the air box was?! Your like a mad scientist or something! Now I want a damn welder on my car! Make sure to post those pics!|
