I have a jeep 4.0L i6 in my 03 wrangler sport, what kind of improvement would you expect? Also, what will this do as far as emission standards?

First you need to know you will need to get a kit with a chip programmed for the Jeep specs. You can expect smoother idle, better take off, lower emissions, and fuel savings But you have to have your water to Koh ratio right and the Volo chip... The only thing I'm not sure of is smog inspection I'm in California and if the smog tech wasn't cool you might fail inspection do to smog equipment tampering / modifying... But my car is smog exempt so I'm not sure

I tied in my cell into my 06 ford escape and I realised a 20% increase in my gas milage. Emission were not tested however I know they were reduced also.This could be increased had I purchased the EFI version instead of the Carburetor version my increases could have been better. Buy the FI version. Also make sure you get a 4.0L kit or larger for you engine.

Great questions. We see an average increase of 33% in fuel injected vehicles. You can send me your current fuel economy and I will calculate this savings for you if you like. These kits reduce your emissions to almost zero.

Well you can expect engine corrosion and probably degradation of any part who touch the hydrogen ......I already expended 3000 to rebuild my engine.

Not sure about the 4.7 . We put it on a 2003 Dodge diesel and we gained about 4 mpg.

Not sure about compatability , but made a significant difference in my jeep wrangler . Would purchase again.

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.

I did notice a difference, especially pulling the 5th wheel camper. I went from about 8 mpg to 15 mpg with my 6.0 HD

I returned my truck to factory settings passed emissions w\o a problem and then returned it to the high performance settings. Its quick and easy. I didn't want to chance taking the test with altered settings.

a feel good 20%(Performance 92) in my 4.7ho grand cherokee(not a joke), id expect around the same for you, really takes advantage of transmission. Also you will enjoy extra MPG's!

I have only seen slight improvement not mpg, maybe 3-4 mpg more. The big improvement comes from horse power and torque.

I did a few things all at once, adding the Airaid was one of them along with cat. back exhaust system. I do get a little better gas mileage, I have less low in torque but more top end. I am happy with it overall, it did change the sound of the car a little. I don't know if this helped at all

Can't speak on 4.0 but my 3.8 (08) it made a huge difference! Shifting problems were solved. Better acceleration and highway speeds. Definitely made a better vehicle to drive.

As far as both questions go I can't give you an exact number on both gas mileage and horsepower. I did feel an increase in power since the intake does make the engine breathe a hell of a lot better. As far as gas mileage goes I did see an improvement but couldn't tell you how much as I didn't pay attention to that after I put it on. AS far as the intake itself. It sounds amazing.

Maybe letting more air in will increase mpg slightly but it's mainly for adding power. Sounds awesome and u feel the car pull more.

the only way you'll notice big differenceis in performance mode though you have to run 91 or above octane and you will see you at 1 mile per gallon increase with better performanceI haven't used the towing mode but both 87 octane and the fuel mile saver I haven't noticed any difference I bought this mainly to turn off the Active Fuel Management System which it does perfectly

I had to tweak the carb on my 06 Sporty. If you have EFI then it too will need some tweaking. And I installed Screamin' Eagle air kit. More power instantly and way more responsive. If you do one you gotta do em all.

I have a 2012 iron, put a k and n and also bought a Vance and Hines fuel pack to go along with the new intake. Also had a new exhuast from American custom that is way louder than stock. The three together have made a HUGE difference in power, especially in the low end. If your going to buy it, get the fuel pack to avoid running to rich or lean. That way you get the best power out of your new filter.

I replace it were my catalytic converter went on my 95 jeep 4 cylinder and I couldn't be happier. I had put a 600.00 magna flow exhaust system on it and hated the way it sounded so raspy like a bubble bee. This eliminated the raspy sound and gave it a deeper more mellow sound.

Sorry, I can't answer this exactly.My car was an Accord LX 2001. I learned afterwards that the emission standards in NJ, where my car was bought, was different from neighboring states. That's the only reason I needed this one. I suggest you check the exact engine type as it could vary from state to state and is not totally determined by the make and trim of the car.
