Cold Air Intake For 06 Liberty CRD.....

onthehunt · **Posted:** Thu May 25, 2006 7:25 pm

Can't we all just get along!!?? I accepted the fact that most people do not know how to work on any engine and now spend their time looking for easy bolt on stuff that rarely works as advertised. It was a legit question posted by one who doesn't know better. You guys came down on him pretty hard I thought. If you don't ask questions, how will you learn? I like this forum because of the civility. I'll write this topic off as someone having a bad day before they logged on.

I don't think asking a question, stupid or not, should subject anyone to ridicule. Nobody knows everything. I've been around diesels a long time. Most have been naturally aspirated, only a couple of turbos. When I joined this forum I knew the turbo in the CRD was variable geometry, but I didn't know and simply hadn't thought about it not having a wastegate. I learned that here. That is why I'm here. Yes, people should take the time to read at least the most recent two or three pages before posting, but if they don't so what? Yes, new people all tend to ask the same questions, again so what? A FAQ sticky would help a lot of that. I have no patience for political correctness, when the situation calls for it, I'll call a spade a spade. That said, I subscribe to the theory that the only stupid question is the one not asked. Consider this too, if someone posts a question here it is something of a compliment. I wouldn't ask a question or visit here if I thought the site was full of idiots. Cheer up people.

I agree. The question was legit. The answer was out of line. I edited my response to make it clearer.

I agree that we need at least 3 or 4 more stickys. The same questions popup over and over again.

Thanks for the link Pablo. Sorry for not doing a quick search before posting. Maybe that should be the next sticky. Heck that may already exist---guess I should do a search for it :roll:

JeepmanCRD,
To answer your question, the diesel engine in any configuration runs with a higher air to fuel ratio (more air) than a gas engine because they are compression ignition fired. Hot oxygen has to meet direct injected, atomized fuel to burn. Literally the fuel has to wonder around in the combustion chamber till it finds oxygen to burn with. So the bottom line is the available oxygen level in all diesels is many times more than in the gas engine. Cut out your stock muffler and put in a 2.5 inch glasspack or one of the free flowiing ovals and you see better results with a lot less money outlayed. No need to change the exhaust piping.

I want to know what you meant when you said "open up the exhaust"? What exaust mods are the best for the CRD? Who makes them?......HJ

Get under your rig and you'll see that all the piping from the turbo, thru the converter to the muffler is 2 1/2 tube, than DC slides a smaller diameter tubed muffler in the pipe and welds it up. The rear is slipped in the tube also and then is 2 1/2 inch again to the rear. Cut out the muffler and the tube attached to it so that everything is back to 2 1/2 tube than replace with a 2 1/2 in round glass pack, or a performance oval like a Flowmaster, Magnaflow,etc. Read the recommended installation instructions for your muffler install. Weld everything back up with an extension of 2 1/2 in tube to fill in if you have to and your done for half the cost of a cool air intake that won't help you anyway. They all seem to allow more dirt to enter your engine which is a BIG mistake.
Now your turbo will spool up faster removing some of the turbo lag and improve performance.

Here's a cheap way to make the intake less restrictive: http://liberty.eurekaboy.com/airboxmod.htm

Stan, I'm sorry I'm posting (I said I was trying to be silent) but one of the other forums (not edmunds) still doesn't get it. Even talk of winter road salt? stains 3/4 of the way up the airbox. Can you post a picture with the hood closed and the rubber hood seals sealing off the "open" space you see with the hood open to show everyone where the air really enters at the bottom of the grill on the passeger side up behind the deflector around the bend and then into that stupid four sided tube, hence vacuuming the road of everything including water.

I too think it was a legit question and if you look at the aftermarket for the diesel pickup world there are plenty of intake performance parts out there. While the stock intercooler does cool the air, there are companies like Banks that provide a more efficient CAC and smooth low restriction intake piping to help more and cooler air into the engine. While exhaust is easy to understand, less restriction means less pumping loss, the same is true for the intake tract as well. This does include the air filter as well. In the oil field you are required to have an intake shutoff on any diesel that goes onto a site. If there are combustable fumes the shutoff basically will clamp off the intake, stalling the engine. You can't tell me that you don't get the same effect from a highly restrictive air box and air filter, the premise for the original question. Not saying the CRD has a bad air intake design, but I'm sure that there is always room for improvement.

It's nice to see that this forum is still providing a wealth of great information. The rude comments and smart booty remarks would be better suited to a more adolescent forum.

Mea Culpa! Three pages ago I provided an apology. At this point it's just fun watching how long this topic is beaten into the ground. It's quickly turning from a cold air intake to a hot air exhale. About the only informative post was from TIRED_OLD_DAVE on how he modified his airbox and his website that showed how it's done.

Inet_CRD · **Posted:** Tue May 30, 2006 10:27 pm

True enough, no need for the last part of my post. Something more relevant would have perhaps been links to intake products (if any) for the CRD.

Hahahahahaha!!! Good one in deed.

What the heck was this thread about anyway??? I started to look back to see if I made an stupid of myself and decided I didn't need to know if I had another "grouchy old man" attack.

Life is too short to get excited, upset or stay upset about anything said here on these forums.

JeepmanCRD asked about mods on how to increase cold air intake. Old man DZL had a moment of rudeness and came down hard. A Bill O'Reily type apology followed as the old fart realized that the point of reference these youngsters have is just fuel injected gasoline engines.

I did the eurekaboy modification above and not sure if it helped or not, I also put in a AFE high flow drop in filter. Only difference I have noticed is I can hear the turbo whine a bit. On my 92 Dodge I made my own cold air intake and got more power and 3 more MPG. ON my 40' M11 Cumming motorhome, I built a ram air set-up and got alot more power and .35 more MPG (which helps when you only get 8mpg).
I am still thinking about building my own CAI for my CRD.
from research, I will build it around a AEM 21-2019BF dry filter.
This filter will clamp right onto the existing air intake hose, once the filter box is removed. I have the GRD eco tune and this shuts off the check engine light for the 2 sensors that are in the filter housing, so they can be up-plugged and taped off.
The trick now would be compartmentizing the new filter so as to seperate it from the hot air in the engine compartment. I was thinking of using a bucket or something similiar to accomplish this.
When talking to the tech at Green Diesel, he felt that it would make a difference in the winter, but the hot air in the summer would make it less efficient in hotter months or climates.
For what its worth: Bob

I've posted this before but, I used the K&N heat shield for a 3.7L Lib (just called K&N direct and ordered it from them), a 4" inlet filter, and a 3"-4" exhaust adapter. I deleted my maf. Works great, don't think it added any MPGs but it made the turbo nosier and maybe a little faster on the spool up.

I looked everywhere. AEM use to make on but discontinued it. Hope this helps

This mod is far better than a cold air intake. Its proven to work on a Jeep product.
