#15206 of 23397 Banks / Mopar / Borla header / exhaust for '03 4.0l Wrangler
Nov 29, 2004 (9:40 am)
We have a 2003 Jeep Wrangler Rubicon Tomb Raider with a 4.0 litre + 4-speed automatic transmission with 6,000 miles on it that NEEDS more power so the transmission doesn't downshift on small inclines and/or in strong headwinds.
I'm guessing I should get one or all of these to get this engine to produce more power:
1. K&N FIPK-II intake
2. Banks / Borla / Mopar header
3. Banks / Borla / Mopar CatBack exhaust
Cost is not an issue but I want to be able to hear my Sirius satellite / Jeep RB1 navigation radio at freeway speeds (70 - 80 mph).
Please let me know what your experiences with these products are so I can make the best purchase decision and give this Jeep the power its lacking.

It doesn't need more power, it just needs to switched out of overdrive in those situations.
The only way to make a significant power increase is to either enlarge the bore/stroke, pressurise the induction system with a turbo or supercharger, NOČ injection, or use a combination of the above.

I dont' have one,, but i have read that the K&N filters allow alot more dirt / grit through to the engine than stock intake.

I agree. I missed the four seasons, especially Fall. I have friends in Vermont and I visit in Oct as much as possible. I believe (or it seems like ) Vermont has more dirt roads than paved. They are functioning roads for everyday use. Anyhow, I did missed the trappings of home so it was goodbye Hawaii.Anyone know what state has the most dirt roads (legal dirt roads)? Perhaps Maine? West Virginia? Wyoming? Go Easy, John

OK....I'm all ears here. I know the blower is working due to the cold air pumping out of the correct places. Where else should I look? Thanks for your help, Macster! Also, recommend a good reference manual? Thanks again!

Paul- I'm in Edmond, north of OKC about 20 miles. Moved here 7 yrs ago from Indiana.
I'm glad to be back in this forum - - it's amazing how many of you have been here for so long! And yes, I think tsjay and I got our jeeps about the same time. Wow - he's certainly come a long way from his "paper towel days", hasn't he?

"Everything looks so pristine, there's few people around, and you are the first person to make tracks in the snow."
If John lives anywhere close to me he's certainly not the first person to make tracks in the snow. It's very crowded here in the middle of the state. The NW and NE corners are much more remote.
I was on vacation (just went back to Ohio for Turkey day. Definitely not Maui) so I'm catching up on all the posts.
I have the Arizona mount and a 3ft firestick. It's very easy to remove the antenna when you need. It just screws onto the mount. It is very rigid when in place, I think it would take a pretty hefty branch to bend it.
The manifold issue: I know why DC hasn't issued any kind of recall ($$$$$$$$). Doesn't it seem like they should. This seems to be a problem that we (owners of 2000 and less) will inevitably
have to deal with, and not a cheap one at that.

The blower isn't connected to your problem. As I mentioned earlier, the air is heated by diverting it through the heater matrix with a flap called the blend door. As it's name suggests, the blend door either partially or fully diverts the airflow, and its position is controlled by a stepper motor, which is in turn controlled by the temperature knob on the dash. Either the dash control, the motor, or the wiring is faulty..........or the blend door is physically stuck.
The only sensible source of information is the Factory Service Manual (FSM). You can buy it in printed form or CD from DC, or subscribe to it on the web at http://www.alldatadiy.com. Pirated versions are also often available on eBay.
