Cold air intake or a chip?
I just bought a 2004 Grand Cherokee with a 4.0 inline 6. I was wanting to get a few more miles to the gallon (I am currently getting 16), and I can't decide which route to go. Also, does anyone know anything about the aFe cold air intake? I have never heard of them and was wondering if they are just as good as K&N. The chips that I looked at were the jet chips. I just don't really trust the other chips that you install under the hood and then the instructions stake to not put them in a hot place... Thanks for the help and advice!

I'd say go for the K&N CAI 57 or 77 series first, and then a Superchips programmer bro.

16 for highway? I usually ot 18-20 Highway but that depends on your foot. Check your plugs(If they are bad change them), check your Air Filter, Replace your Fuel Filter, Make sure you tire pressures are correct.

Re: Cold air intake or a chip?
I definately haven't been driving it like I drive my tacoma... But it is on and off the highway. I just got with with less than 38k miles on it so I was thinking it may be the spark plugs. I saw that other thread, but no one really said what kind of core to get on the plugs except not to get the platiniums or whatever. I really would like it to get around 18 around town like my tacoma got, or as close as possible.

Has anyone tried the 70 dollar chips that come up on the google search? They seem easy to install, but it just really looks like a pot that changes the resistance on the mass air flow sensor.

Just get the recommended ones. My 04' WJ has 184,000 miles. I'm still driving it.

Don't get a "Chip" because it's not worth getting.

Re: Cold air intake or a chip?
go with the superchip programmer that what i have... im suprise sometimes what good instant mileage i get sometimes 20-24 going about 70 and 22 going about 50-60 but i dont drive at a constant speed that often so my mileage is bad lol

Chances are the chip will make the biggest difference to MPG. With the CAI you'll get a MPG or so, but at the same time become addicted to the sound and won't ever be off the loud pedal!

Although, you may also enjoy the 10 or so extra ponies from the chip and be in a similar situation. It's gonna depend on your discipline really.

Re: Cold air intake or a chip?
Yeah the minute I put my CAI in my 99wj i went from 15 or so down to 9-10 because I drive like a retard on crack. No offense to any retards on crack but it's amazing how much discipline I lack haha.

BTW funny video on subject kinda...

Re: Cold air intake or a chip?
Ok.... So I changed the spark plugs this weekend and learned how it drives when you miss one of the spark plugs in the boot... I'm a retard on crack.... I know. I've only driven it about 30 miles since. And the story gets better. I love the Jeep... But the place I bought it from is kinda turning me off. They did an oil change after I signed the papers and filled it about a full quart over what should have been. Now I'm really glad that I got the extended warranty because the oil pan is now leaking, along with the main seal and the tranny pan. It's covered by the warranty, but I've had it all of 10 days. I hope that this is just a fluke and I won't have it in the shop too much.

BTW... Unholyskorn86, I would have talked to you about the cold air intake, but I can't PM people since I haven't posted enough. I did get one off ebay for $145 shipped... But I would have really liked to help out someone that gave me some info. And that's real southern hospitality....

Re: Cold air intake or a chip?
Ah yeah you need ten posts to reply. I'm just glad you got something. I hope the shop does it's job fixing everything. Just take it this way tho, if they don't fix it go to the dmv within 30 days with the copy of the warrenty and make a complaint.
