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.

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

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

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.

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.

You ever try to pick up a tool out of a toolbox that is usually right at 210 degrees or close to it?

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

Check your connections and retighten as necessary. Anytime I put an intake on anything I snug down all the Philips screws (should also be like a 5/16" socket). 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 think I've found it. The problem wasn't with the cold air intake at all. Pulled off the intake and tb and tracked the noise with an electric stetho. It's a leaky manifold seal. Im pulling it apart after work today for a new gasket and some copper coat. Thanks for the ideas on fixing her!

Installing an aftermarket air intake onto a 4.0L engine is, in my personal opinion, like inserting a big funnel into your mouth in the belief you'll be able to breathe more air in and thus be able to run faster.


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

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.

Lol. Reminds me of a story i heard about my step dad when he was a kid. Had a 66 gto with a 389. Tried to race a galaxy with a 406. Galaxy whooped him first race. Double or nothin, he gets out and takes the air cleaner off. Galaxy whoops him again. He didnt even stop, just kept going.

Since we're reminding each other of stuff, here's a good one. At age 16 or 17, my dad let me borrow his 394 Olds Starfire which was a pretty hot car for its day. My buddies and I were out when one told me to take the air filter off which made it sound awesome to us kids. I forgot to put it back on. My dad drove it to work the next day and noticed the difference in sound so he popped the hood. Upon seeing the missing air cleaner, he assumed it had been stolen so he told the insurance company who bought him a new one the same day. When he got home and I told him I had actually removed it the night before, he freaked out and hid the original air cleaner in the garage for fear he'd be arrested for insurance fraud.

I can't believe that you really think that speeding up the air, before it goes past the air filter, before the intake bends, and even before the throttle body, has anything to do with the combustion properties. It's not a swirl dam in the heads.

I love those Starfires. Very cool cars

Jerry's point is valid. Speeding up the air prior to filter etc, will fill the box , tube and plenum with more than enough air to satisfy the motor. Remember, a motor is just a vacuum pump. You could have a 55 gallon drum for a CAI and it will only pull so much. Just because ive got a glass of beer rather than a mason jar, i cant drink it any faster.

No it's not. Anybody with low to moderate knowledge of engine combustion dynamics will laugh at his statement of a horn before the air filter causing better combustion. It's along the same wacky lines as the vornado.
