Hey guys. I joined this forum a few years ago when I got my Jeep Commander and browse sometimes but I'm not too active. I was wondering if I could get some input on something with my Jeep. I'm not much of a car guy but noticed the other day jumping my battery that there are two cylinders that look like they used to have some sort of tube between them. I'm 90% sure this is my intake to the engine, and that for who knows how long my engine has been taking in unfiltered air. Does anyone know much much this duct would cost to buy? I was thinking that might be something people mod so maybe I would have some luck in the WTB on here. Car seems to run as normal but should I take it in to get engine checked out? I have NO idea what happened to that duct I don't mess under the hood and don't do any off roading! Here is a picture of what I'm talking about.



Thanks so much!!

Chad

On your 3.7 that is the air intake from the air filter in the left box - to the engine intake on the right. Yes there should be a part/tube there. Right now you are not getting any air filtering - sucking in all the dirt:( I have the 5.7 so can't provide a picture of what you are missing. Someone here should post a picture of the 3.7. Yes you should fix it and your may have caused some engine wear running without it, but not knowing how long it has been that way - ??? Would not worry about getting the engine internals checked, just keep in mind what you have found and tell any mechanic in the future that it was running on unfiltered air.

That is an important piece! get it and put it on!!

Now, just looking at the pic I do not think you have been without it long. The Sherlock Holmes in me says that the lack of dirt/dust at the mounting flanges of the intake tube suggest that it has only been missing for a short while.

Have you had any work done lately? Tune up? New air filter? If so go back to that garage and rip their ***hole apart!

Thanks for the replies. I called the Jeep dealearship and they said the part was only $36 so that's good. Does anyone know if I can just pop it on myself or does it use clamps or anything?

I had some body work done on the front 2 months ago but they didn't do anything with the engine. That's the only thing I can think of because I for sure haven't messed with anything! I figured 2 months later it would be hard to call them about it and being only $36 probably not worth it!

You don't think I should get my engine "cleaned" or checked out? I imagine sucking in dirt and dust can't be good for it but like I said I haven't noticed it running any differently!

Thanks again!

It's easy to put on..it's installed with clamps...like hose clamps...It would take about 5-10 mins to installed. I would not really worry about it unless it starts running rough or a check engine like comes on.

Short term, you should be fine, but it's something that needs to be fixed. I'd go back to the shop and ask. Of course, they'll deny they did it, but it's still not too bad. You don't have to get that part at ther dealer. As you can see in this picture of mine, it's just a flex tube. You should be able to pick one up at your local parts store.

Oh my, LOL. How crazy to lose that piece and have no idea where it went! But yes, that'd be the first place I'd go is to get that tube and get it on!.. in fact, I have my stock intake assembly sitting out in the garage, so if you somehow can't find the part, I have it.

With that hose missing all the air going into the engine is not going through the air filter. It is a big deal if something big gets into there and through the intake.

Thanks! I think one of the dealerships has it but if I can't find it I'll let you know!

I understand that it's important to get the tube put back on but do you think I also need to get my engine cleaned or checked out even if I haven't noticed anything different yet? I assume I would hear or notice something if anything big had gotten sucked in.

I understand that if something BIG went into his intake, it would defintely mess up something...I was just adding my .02

It would be difficult for something big enough to do damage to your motor to get in there, but anything is possible. You shouldn't even worry about it since that possibility is so unlikely, but of course, get it replaced sooner rather than later.

Just to calm your concerns a bit, get a flashlight and shine it into the box the tube attaches to. The one that mounts on top. You'll probably see light dust, but not much more.

Honestly, my 4.7 intake looks the same as that.

If ya don't want to buy a shiney new one from dealership, you could probably get away with a junk yard find. With a 3.7 or 4.7, you could look for some Rams/Dakotas as well.

Autozone has some universal 3" ones for $20 but my dealership can order one for $36. I don't mind used as long as it works!
