Answer 1

I have the KN intake and while my gas mileage didnt increase substantially I did pick up way better throttle response. It got rid of that hesitation you feel when you gun it at 45mph. (i test drove 3 new 04 Rubicons and they all did it.) So assuming you do not beat on it more to hear the who00000ose. yes will get a little better mileage. I would also throw on a performance muffler if you haven't already.. every little bit helps

Answer 2

people say it does, it doesn't, but either way it is such a small difference that you wouldn't know it. What is good is that those mid level performance filters do give you more horses and some of them have a 1,000,000 mile warranty if you make sure to clean then, so you get performance and save money in the long run. If your looking to really pinch pennies on gas then try a product called cyclone, it will give you a small amount more power and cut back on gas, and is very simple to install. Also the usuals like tire pressure and tune up and so on if your looking to be helped out with gas

Answer 3

Went to the above site..14 HP at 5400 RPM on four liter???..Interesting...red line is 5000.

As the new filter has a SMALL shield to TRY to get some cool air, which it will not, it could HURT your normal mileage due to induction of hot under the hood air.

I have run chassis dyno runs with a CLEAN filter and open throttle body and seen basically NOTHING at the rear wheels.

How many miles would you have to drive to pay for this thing if you got 1 MPG?

What engine? If four liter consider SLIGHTLY larger tires to slow down the engine.

More expensive based on experience with 4 liter Cherokee and 28" tires, is axle ratio. 3:73 from 3:55...lost 1.5mpg..Ok Ok...more fun though!!

Good Luck

I'm not sure how efficient that thing is to begin with, seeing as it isn't that new anymore.



Jeeps are infamous for gas milage as it is.



I'm a big fan of after market air intakes. They help the engine RUN more efficiently (volumetric efficiency), but don't necessarily get you better GAS milage.



Think of it this way: Go run around the block.



Now go run around the block with a ski mask on. Obviously, to run at the same pace, you're going to have work HARDER to run with the mask covering your face.



i.e. You're going the same speed, travelling the same distance in the same time but you're working harder to do it because you can't breathe efficiently.



More air does mean more fuel, but the more efficient your engine runs, the more efficiently it will consume fuel over the long-haul.



Plus cold-air intakes sound wicked.

Answer 5

Years ago there was a thing known as a cool can. Using an empty coffee can. Coil fuel line inside, leaving the center empty. Make it so you can connect it to your existing fuel system line. After it's hooked up, fill the can with dry-ice, and put on the lid. That will improve performance, not for use on the road. It's poor man's N2o. You also buy gasoline early in the morning for the same reasons. Condensing air on an injected system that is newer than1996 is futile to begin with. If you are actually seeking ways to regain those controls, you need a carburetor.
