    let me know if the fuel is any better but u said the power feels more wonder if i just change the whole cold air intake if that will be the same

    Mpg doesn't improve with less intake restrictions.

    I second this statement ^

    I've been monkeying around with how the intake is put together, right now I have the snorkel hose that goes to the fender off and i put a reducer coupling on where the corrugated hose connected. I reduced down to a 2.5" hole.

    I'm thinking by removing the corrugated hose i have changed the torque

    Is my thinking correct in saying that you can change your torque curve of the engine by changing the set up of the intake system. Intake system meaning everything/anything in front of the intake manifold.

    I also have the Afe Pro dry filter.
    I'm avg. about 200 miles a tank, which i think is poor.

    I'll agree with that.
    200 miles on a tank, meaning only 10mpg?

    Even on a V6 4x4 you should be pulling 16-18 unless you're running 35s and spend all your time driving around town.

    I spend a lot of time driving in town. Stop and go is a real gas killer.
    Was wondering if I kept my rpms below 2000, would I get better gas milage?

    Probably not, and ya, in-town driving is a killer.

    I'll be rolling 25.8 or higher on the Ultragauge with 300 miles on the tank.
    One day, 50 miles, of puttering around town shopping with SWMBO and it'll dump to 23mpg.

    Cold engine also hurts. Start of my commute, the "short average" on the UG will be 14 when I get on the freeway... maybe 18 by the time I'm 10 miles down the road, and finally start peaking around 25-27 depending on traffic after 20 miles.

    Exactly... it's funny how so many people think if something helps their engine make more power, they will get better MPG. That extra power does not come out of nowhere, it comes from the computer adding *more fuel* with the increased airflow in order to maintain the correct A/F mixture.

    This post was an awesome find. I just dropped in an AFE and was trying to pull out the secondary and cracked it. My intent was to check it, clean it if possible, or replace it. This post saved me some grief because tomorrow I will take the secondary out. Nice and Thanks!

    If you take out this secondary fixed filter which looks like it rest directly against the main resusable filter seems like the main filter may get loose because the secondary filter isn't applying pressure to it. On a bumpy road it may move around and crap my by pass through the side.

    I'd like to try this mod but it seems like to many risks for little gain.

    What info do We have on winter gas?

    It plays a part in poor fuel milage?
    And is it not true that 87 octane has more energy than 91 octane with ethonal?

    Right now I've got 200 lbs of sand for winter weight and low tire pressure for traction. So...Its a bad time to make good gas milage.

    I do have a winter-front on the grille to keep the engine at running temps. If i knew that i could get a block heater that would work in my 2010 4.0L I'd buy one. I get mixed reviews on block-heaters.

    87 vs 91 makes no difference in the BTU content.
    Ethanol does reduce BTU content, so yes, "pure" 87 (if you can get it) has more energy and will deliver better fuel economy than ethanol-contaminated 91.

    We have 87, it's $3.67/gal. What do you pay per gal?

    It's more difficult not being able to find the rivets. They stick out around the edge of the filter. You should be able to find them with your eyes closed. Take a look.

    They aren't really rivets... they're just pins that stick through the sec filter and they are melted down with a hot iron tip.
