Well if you are concerned about tire pressure you can fill the tires when warm rather than cold--that way you'll be sure that the pressure will not go appreciably higher. It's pretty hard to blow up a modern tire by adding 5 lbs of air to it IMO.
K&N filters will give you lots of noise but that's about all. You have to look at your car's engine as one long tube---if you open one end but don't do anything to the middle or the other end, you aren't really doing anything of significance. Not just the intake, but the fuel system, the engine itself, the computer mapping, the turbo if equipped, and the exhaust needs modification to make any kind of payback worth the effort.
Modern engines are pretty much locked into their gas mileage. The automakers do make some compromises for comfort and safety and reliability, of course, but they have these engines pretty well dialed in by 2008. They do not leave much on the table for tinkerers unless you want to add serious horsepower for serious dollars and a loss of fuel economy and reliability for that 'fun factor".
There is no "bolt-on device" for $29, no magic fluid, oil and gas additive, turbonator, hydrogen generator, chemical, acetone, or whatever that's going to give you better fuel mileage.
5 quarts of Mobil One synthetic oil would do more good than a whole boatload of them IMO and even that's going to be minimal.
Good tire pressure, driving habits, synthetic oil, alignment, brake check, good tune-up, new air filter, good gasoline---that's about all you can do on a modern car.
Well possibly you could add overdrive gears, change differential gearing, etc, but that ain't cheap.

Gitzennsnorkels and Flackinstackers don't do a damn thing.

Try the Hypertech ECON programmer for your Explorer and see if it works for you. If it doesn't you have 30 days to return it for a full refund. The extra power a programmer will give your explorer will come from it making your engine more efficient. Better efficiency equals better fuel economy. I know a lot of people have a hard time wrapping their minds around the concept of more power and better fuel economy, but once you look and see what it really is things become clearer.

Yep I'm one of those people. I don't see how raising shift points and rev limiter or lowering cooling fan temps gives you better MPG. Also buzz on the 'net seems to indicate "improvements" in mpg that are well within statistical variation. Also the sources of the dyno tests are not given on the website, that is, were they done by totally independent sources?
I could see how this device might make your truck/car more responsive but beyond that, the website's "evidence" is pretty slim pickins IMO.

Aggreed. Generally you can have your car tuned for more power, but even then a chip can only do so much. Usually you will see the most gains on turbo cars, as you can make the piping bigger to pull through more air and raise the boost levels. This will make your milage go down though. Inversely you can also have the boost turned down by the ECU, saving milage but making the car have less power etc.
