is it worth the 250 bucks?

is any brand better then another?

i THINK i saw a few write ups on 'em..

any suggestions?

thanks

ive heard really good things about the xdi tru flow intake. do a search for it on ebay and one comes up for about 309 i think. im looking at getting the same intake to compliment the borla exhaust.

 

aFe makes a good intake also. i have one in a e46 m3 and you can really hear it suck in the air..they are about 180-190, however they arent as mud/water resistant as the xdi

 

Im personally looking into the AEM, It has a Oil free filter that from what i have researched is better for use in the woods. No oil to grab dirt, and easy to clean.

 

are they hard to install? i saw a write up somewhere on here...and that brings m to another question, if i install brand X CAI, am i limited to other air/exhaust mods(i dont' think i'll ever need a snorkel)

 

If the money is a concern, you'll probably come out dollars ahead making your own. There are several threads where people have done just that, and on the cheap, too. In answer to your question, no, there is not one single ready made intake that gives the power benefits that you pay for. The reason is because the stock air box can already flow more than the stock engine can use.

 

The things to remember about cold air intakes, are that:

1) They need COLD air...from OUTSIDE the engine bay/not under the hood, etc.

2) They are INTAKES...so, IF the oem intake was actually not letting in enough air, THEN a less restrictive intake can help.



Hearing the same engine trying to suck in the same volume of air, but louder, doesn't mean more air is getting in, just that the air's PATH makes more noise.

There is a term, critical orifice, that essentially describes at what flowrate the passage will be too small.

If the oem system has a "Smallest Passage", then very little you can do will be able to overcome that limiting factor...Unless you remove THAT point/increase its size, etc.

If the new intake just makes the BELL of the funnel larger, but the flow STILL must squeeze through the same tiny orifice at the funnel's bottom, the final flow rate won't be improved.

This is ONE of the reasons that an intake alone, or an exhaust alone, produces almost no gains at all...there's still a funnel with the same limiting factor/Critical Orifice.



Food for thought at least.

 

I did the AFE and Banks cat back system at the same time. I did notice an increase in performance. And I like how it sounds better. It still isn't a race car (and never will be), but at least it sounds meaner.

I think that if i get around to getting a programmer that will help too. I'm thinking lift kit right now, so I think that the programmer is on the back burner.

Also a little food for thought. your exhaust Will melt that cheep a-- factory bumper. Found out that the hard way.....

If i had it to do over again i think that i would have spent money on the lift first and the engine second, although i guess that I drive the thing everyday, and only off road maybe two to three times a month.


Happy jeeping!!!

 

 

if you have the $$$ go ahead and get one. i had one on all of my vehicles and was happy with them (i had K&N's). in each vehicle, i got about 2 MPG increase with the intake kits. just two things to consider; if you will be making water crossings with your jeep, then you might not want one--they will definitely let water in more than the stock intake. the second thing is make sure the manufacturer has properly tested the intake on a JK--I had a K&N on a 2000 Tundra and it threw a "lean code" causing my check engine light to go on. K&N said that it was letting too much air pass the mass air flow sensor and making it think the air/fuel mixture was off. I had to take the vehicle in to them so they could modify the tube to fix the problem. after that, i had no problems. K&N's jeep line is their most popular, so i am sure they thoroughly tested the JK products, but i can't say for sure about any one else's....food for thought....
