go buy a prius if you want mpg. me, I live for the smell of unburned fuel spewing out the side pipes of the lifted bricks some people call jeeps.

the best way to get the most power and gas mileage out of your jeep is to keep it maintained properly. change your plugs...cap and rotor..good wires, keep your motor oil and other fluids changed regularly....i've got a cone air filter and that seems to work pretty well...not so much for insane power upgrades but at the very least to increase the amount of air that the jeep can take if it needs it. the relocation of the intake air temp sensor seems interesting though....could be an idea

It does actually work. Jeep figured this out in '04 or so and implemented it on the 4.0. If you insulate the intake tube it works more betterer. You can use a IAT from the newer models and just leave the threaded one in the manifold as a plug. PEP BOYS and such sells a kit to mount the new style press-in sensor. It works and is cheap. I have an '06 so it was already in the tube close to the throttle body, but I have a steel intake tube and a cowl filter. I insulated the steel tube with header wrap, but would like to add more insulation to keep it all as cool as possible.

i dont no about those tornados ive heard nothing good about um

jim92 · 02-04-2009, 05:36 PM

go on hesco.us they have aluminum heads, high flow water pumps, air inductions cams etc.

dont get a throttle body spacer or a tornado fuel saver cause you cant have the air going in a vortex b4 it hits the combustion chamber or it will lead to some problems

i sudjest an air induction ,that will wake ur 4.0 up

haha best free thing to do to a Jeep is to take the carpet out and top off, save some weight, do'nt worry about aerodynamics, Jeep lost that battle in WW1

change spark plugs, flush fuel delivery system, use synthetic oil and oil booster products, use high grade reg. unleaded such as 106. i get 27 mpgh and 24 mpg in normal driving. high grade unleaded is expensive but it is worth it when on long runs and trails. if u have a YJ fix the fuel hose prob in the gas tank. its really 20 gal. not 15. build a spare vertical 20 gal reserve tank in the back with delivery system (w/ on/off switch) from trunk to tank under rearend. build an intake of ur own for 10 to 40 bux (may as well build a snorkel while ur at it). if you can pwer shift without the clutch (i wouldnt reccommend that as it will !@#$ ur tranny if you dont time it rt). i dont know of anything else other than swapping turbo dieel 4 cyl. in ($$$$$)

Wow. 3 years later, this thread is still going strong.

No it's not it died almost 2 years ago

I heard clocking Flux Capacitor 2deg. East will get 5hp 6.5 on a cold day.

What is a tornado? o_O (The non-Oz kind?)

I've noticed that replacing my horrible air filter and running the "engine" cleaner stuff through it gave me more power. But you don't want to run your engine on that. Mostly, it was a way for my jeep to tell me it's time to change the spark plugs.

Just keep up with the general maintenance. I haven't heard of anything to increase power/mpg (it is a Jeep after all.) But you can minimize the power/mpg that you will *lose* with normal driving wear/tear.

/note to self. Check thread "use by date" first!
