Air Intake

[ender00]

What is the best-bang-for-the-buck / easiest-to-install aftermarket air intake for the LIBERTY? Would a cold air be worth it or even available?

 

[jfortier777]

Better stay out of the water if you get one.

yep....

K and N, FIPK
Volant...
and a few others..

Rustys KJ airtube gets rid of the air box, keeping the main tube to the throttle body which is fine. And it's easy to remove and go back to the OE airbox in case you're going off road. Plus it's half the cost to the other kits.
I suggest the 5x8 K&N filter.

Rusty's intake seems to me like a good deal... I haven't gotten one, but it seems pretty good. At least the best bang for the buck.

Well when you think about it, the most restrictive portion is the box itself. And if you know you're not wading through water, it should be fine to install a intake kit.
But I thought, why am I going to spend $200+ for a large tube, Liberty already has one, and a open filter element.
So Rusty's one peice, has the emission fitting and replace the box, but is extremely replaceable. I spent money on one element, the 4x5 and it was very small after installed, so I bought the 5x8 after making careful measurments. The 5x8 misses the ac tubing and looks nice and large.
I've had K&N kits, but this seemed much more logical.
I'm all about old school HP mods.

thanks

muchos gracias! looks like that is going to be the kit for me. dont see how the other $200+ systems are worth the money. rusty's looks like it will do the job just fine.

200+ for K/N or AEM, or $65 on ebay for one with a heat shield??? even if the filter is crap, you could still put a real K&N on for less $$$ than the K&N Kit. Has anyone out there bought one of these???

Okay, what year is your Liberty? Those intakes only apply to 02-03.
04+ they (DCX) moved the IAT sensor back by the throttle body, attached to the intake tube. You need to keep that functioning or there will be fault codes. Go get the Rustys Air Tube, it's the best "bang for your buck" out there, with no larger than a 5x8 filter from Summit Racing. Any larger than 5x8 and the element hits the ac tubing.

I wanna bring this topic back to life.
I don't wanna go with very expensive ($250) K&N. Is there any cheaper alternatives for better flowing air intake? Or Should I just replace the filter in stock box with K&N filter instead of the FRAM I have now? Will that make difference without letting the dust into the engine as stated above?

I still thought that Rusty's kit was a little expensive for nothing more than a tube with a barb fitting and a mounting brace coming off of it. So, I did a little investigating (walking around Menard's and Fleet Farm with a tape measure) to see what would fit the opening of the stock Jeep intake tube. I checked out short sections of muffler pipe and of course the plumbing PVC isle, but no luck. I ended up checking the plastic electrical conduit section and found that there was a 2 1/2" coupling that had the correct outside diameter to approximately fit inside of the stock air tube, it's exact size escapes me at the moment though. I then found an AEM 3 1/2" cone filter on e-bay for a great price. For the attachment method, I had an 1/8" thick by 7/8" wide strip of aluminum that I measured to the correct length including a right-angle mounting foot. From there I bought a 3 1/2" U bolt and drilled two holes in the aluminum strip so that the U bolt held the short length of conduit in the correct location. I chose to attach it to the same point in the engine bay that the Rusty's tube attaches, why come up with a different spot if someone else has already done the work for you. For the valve cover breather tube barb, I bought a brass tubing nipple (3/8" size) with the other end being 3/8" threaded. I drilled a 3/8" hole in the conduit coupler, screwed in the barb fitting and attached the stock breather tube to the barb. Thats pretty much it, tighten the hose clamps on the intake tube and the filter and you're all set to go.

Now, here's the pictures:

Total cost:
*Cone filter - prices vary
*Conduit coupler - $1.25ish
*Aluminum strip - $8.00ish
*U bolt - $1.50ish
*threaded/barbed brass hose fitting - $2.00ish

Not including the filter, the whole think shouldn't cost more than $10-12 to make on your own.

Here's one on EBay for an 02 with a heat shield I'll prob get:

Don't know bout the filter, will invest in a real K&N.

So....spend approximately $30-40 plus another $12-15 on shipping for a tube and filter (which you're going to have to replace within 2-4 months) or $10-15 at the most for essentially the same thing, with out the heat shield. Plus you start off with the filter that you'll end up buying in the long run with the e-bay special. All's I'm sayin's is keep some of your money and experience the same gains. Thats what this thread is all about.

If its the heat shield you're interested in, give me a couple days and I'll have a template whipped up to make your own out of a piece of thin sheet metal. I'm not trying to bust your biscuits, just trying to save you a few $$$.

Here's an example of the custom intake and heat shield I made for my '98 Grand Cherokee Laredo (5.2 V8)

What gains are we talking about here?

 

[wildrussian]

Where can I get that 5X8" air filter that Trodo was talking about

From Rusty's Offroad:

Rusty’s Air Tube is one of the best things you can add to your vehicle. The air tube can be installed in about 10 minutes and will deliver 5 to 10 horsepower and will greatly improve fuel economy.

I see no reason why my version of the air tube, if paired with a high quality filter, couldn't achieve the same type of results. I don't know how scientific Rusty's numbers are. Some intake makers like to slap on over optimistic gain figures.

 

[Argent]

even with the OEM tube with all it's krinkles in it will cause turbulace on the inflow and thus a measure of resistance (which is bad as far as being able to introduce the most air effeciently in to the engine) Ideally you'll want a smooth bore tube like the K&N setups....I'm sure they can be made for cheaper with other parts.

 

[JeepJeepster]

A drop in Amsoil or K&N will probably do better than a cold air intake. Those usually take performance away since they suck in more heat than the stock air box does.. Even with a heat shield.. I would stick with the stock air box..

Buy an amsoil filter and be happy Huseyin!
