I have a 2003 TJ with a 4.0L engine and a 5 speed manual transmission. Is this a worthwhile purchase? Will I see better gas mileage?

I have a 2010 JK with cold air intake and larger tires and it did make a noticeable difference. The shift points have changed and at freeway speeds I am not having to floor it to make it up some hills. The throttle response has improved too, not a kick in the pants difference but one that you can tell. As for mileage, I measured it for 3 weeks before I programmed and I was getting about 17.1 mpg after the tune I was getting 19.3 mpg. I drove it the exact same so I can say with 100% clarity that for me it did improve the mileage.

I found it to be a waste of money for my '05 Rubicon. The options available for TJs and older Jeeps aren't worth the cost. For newer JKs it might be a worthwhile purchase.

I have an 04 grand Cherokee (automatic unfortunate). It did little to nothing. My driving habits made a difference. The effect of it are unnoticeable. Sorry to disappoint.

I would suggest looking up your 2001 T&C; on a place like autozone and get the part number then do it for the 2005 T&C....; if it is the same.. .you are in business!

It should work no problem the taillights for the tj are the same throughout the years

my '95 k1500 has 273k miles and i installed it. still need to rebuild the clutches and band however, but helped my truck push my 35's on the stock 3.73 gears noticeably.

I only know that with the 4.6liter I have performance went through the roof and I get about 15-20% increase in gas mileage. considering that the 4.6 is a converted 5.0l I don't know if you will get an increase in the same or better way that I did. you may want to go to www.hypertech.com to get the best information.

Very few features for the TJ. Save your money as I found out too late on my TJ. Now if you have a JK it has plenty of features and the most if it is 2012 or newer.

not entirely sure but your going to go through a whole lot to get it to fit correctly with your exhaust with little gain, and with and auto you wont even notice the gain because its in the top end which without a manual you're not even going to be hitting 5k plus rpms. save your money and swap the tranny first

I have a 2002 tj and it fit perfectly. No grinding or modifications needed.

I have an automatic and by using the 87 Octane tune I improved my mileage by about 4 or 5 mile per gallon. Plus it performs much better as far acceleration/much peppier. Also went to a larger tires and wheels re-calibrated for the new height and it corrected the speedometer. So everything I did was an improvement over stock, so I would say it would help with a standard also, but not totally sure.

If engine is still 5.4 triton, I would go with it the price is still more than half of OE coil anyways and considering other options almost none, be silly not try. Most import thing is to measure seat ht. Compared with other plugs

Yes. 2003 V6 AWD, 260K miles. Previously had no specific problems with our Highlander transmission but after reading reviews on Lubegard red felt it might extend the life of the transmission as the car is in excellent shape dispite the high miles. The result, I am pleased to report, is much-much smoother-quicker shifts. I had no idea how "raw" the transmissoin was shifting until adding the Lubegard. Night and day difference. Shifts are almost imperceptible now when cruising at normal speeds. So smooth. Also the car downshifts more readily so it no longer lugs the engine on inclines. I am not one to favor additives but this one is the exception. Highly recommended. 31 October, 2015. Lorilou. Yes. 2003 V6 AWD, 260K miles.

I would only buy it as a cheap replacement muffler. It won't give you any noticeable power or increase your fuel economy! Some like to think so but if there is any savings you would probably be lucky to offset the cost of the muffler in the lifetime of the vehicle.

I also have a Dodge with the 5.9 Cummins, stage 2 cold air intake with a straight pipe. We must have identical trucks, but mines an 05. All I can say it that I ran the smart on performance which adds 100hp to your 325 making it 425hp, and boy does it make a difference :) (ran it on performance for about a year) . With that being said I just changed my trans last week, lol. Got a complete rebuild all heavy duty parts for 2500$, with the dodge tranny you will probably be doing the same thing. Also, I'm 33 so I didn't do a whole lot of "beating" on the truck. Just your average race hear and there. ;)

I have a stock TJ and it works fine. With that bike you should be ok since it's pretty light (I have the same one!). You'll just have to push it up a steeper slope since your Jeep is so high. This carrier doesn't have the best tie down options though.

you won't go until you engage the belt with the handle be a bit gentle putting it in the gear you want. you don't have to bull and jam, the transmission does not have synchromesh gears it appears to have straight cut gears be nice. I got mine around June and probably have at least 100 hours on it.

I'm running 33s right now and have plenty of room on my 2000 tj. You could easily fit 35s.

I have this same system on my 2000 tj i notice the difference immediately. it has a nice growl and the exhaust tip make it stand out.
