|dmcg||The best thing you can do for gas mileage is make sure your air filter, plugs, wires, cap, rotor, O2 sensor, oil, tire pressure rear exhaust and cat are all good. These are the things that affect your gas mileage and performance of your Jeep. "Bolt on" performance items typically won't make any real improvements. If you have a 2.5L, an exhaust header and freeflow exhaust would be the only thing to help it breathe better. Seafoam is good for cleaning out the system and easy to use|

As for sea foam it's a good quick cheap cleaning, but if you have a Firestone near you go there and ask about their induction cleaner. Just did it to my '87 not that long ago and it cleaned up the throttle response nicely, my MPG's even increased. I payed $40 for it but that's an employe price, I think normal is like $80? But that basically pays labor.|

You should run a can of seafoam through your tank and put some in the booster vac line. That keeps my 4.0l running really well. Also change your fuel filter.
Have you considered swapping to 19lb. injectors?

I just installed one myself yesterday.
I got an AirAid Cold air intake ($260) and a throttle body spacer ($60) and it responds a bit better and sounds sexy!!!!
Oh and I didn't brake any nails THANK G-D!!! Cause I just got them done ! Lol
Btw I posted some lame cheesy vids of how it sounded before and after and also a mini test drive post install.

|dmcg||Jeeps have a nonrestrictive airflow so they breathe perfectly fine. AC delco has the best "breathable" air filter for Jeeps. Don't use K&N unless you want to spend a couple of hours every few months cleaning your throttle body. As for cold air intake, it's actually a hot air intake since it sucks all the hot air from the engine compartment. Your factory air filter housing keeps the temp down compared to the rest of the engine. Spend your money on better things for your Jeep|
