Throttle Body Spacers!?

E-Fan, under-drive pulleys, intake filter change, exhaust, and Programmers.
Focus on these additions first, they are the easiest and and cheapest things to add or change to gain power and MPG. There are additional things you can alter, but until you have done all these things, don't worry about anything else on the market.

Hmmm.
Fuel economy is a very big deal to automotive manufacturers. If a simple device could yield even a 0.1 MPG increase, it would be installed from the factory. Any engineer who could come up with a cheap or free way to improve FE by 1 full MPG would be worshipped as a god. 4 MPG from a TB spacer? No way.

Car manufactures care about profit. And efans probably cost more for them so they'd rather just use a lil more gas up with the old style fans

Ordinary car-type electric fans won't pass desert cooling tests in trucks towing trailers at max GCWR. You really need a higher power fan for that and a more capable charging system than what is standard in a Ranger. Sure, lots of us get away with using electric fans under less strenuous conditions but they can't cut it in severe testing.
Ford could put a massive pusher/puller set up on a Ranger but the cost would be prohibitive, both for the fans themselves and for the charging system to support it. The other choice would be to severly downgrade the rated towing capacity but that would surely cost sales.
In the end, you have to come up with a balance between cost/benefit/sales.

Here's some good reading that shows these "magic" devices to be either worthless or actually detrimental to power and economy.

I find the throttle body spacer idea to be ludicrous. You'll notice that companies make spacers for virtually every popular engine out there. That implies that every dyno facility at every major manufacturer got the intake manifold dimensions wrong and that they are all too short! What do you think the odds are of that happening?
Now I'm not saying that every intake manifold in the world is perfectly optimized. Actually, a manifold can't be optimized for every RPM and load. But you know what? You never see an aftermarket company offering a mod to shorten one. I would think that, statistically, at least once in awhile some of the "stupid" factory engineers would have come with a dimension that is too long instead of too short.
Again, I think it comes down to this: an engine-specific spacer is very easy to make and easy for the consumer to install. Add a few BS claims about mixture enhancement and swirl and you have a saleable product. And that means money in someone's pocket.

this devices just don't make sense especially on a modern fuel injected vechicle..they aren't spinning fuel and air which would make some sense just spinning air ( fuel doesn't get injected until right before the cylinder) only way i would consider one is is if they isolated the tb from heat ( coolant line to tb would also would to be elimitated to get full benefit) however that could cause some driveability issues especially in colder weather- this wouldn't increase fuel mileage though i believe one of the reasons the tb is heated fromthe factry is to increase fuel mileage
