Does anyone have experience with any of these. Do they actually work?

no, they don't produce enough Hydrogen to make a difference.

How to improve Jeep Wrangler MPG:

1. Don't drive it.

2. Take the Camry instead.

If this works like they claim, it would not be so affordable. Look on the "products page"... in the first few pics, they have PowerFist rocker switches and fuse holder.

Nothing has made more of an impact on my mileage than switching to 4-port fuel injectors.
I've increased mileage 20-30%.

That being said, the crap that came out of the fuel rail when I cleaned it and the old fouled out injectors may be why I was getting such bad mileage in the first place. YMMV

i have found one solution. CEL came on 2098 lean mix. Don't know if it's a manifold leak or an O2 sensor but my MPG has gone up from 16 to 18.

Don't know if you're joking or not but running lean is pretty much the worst thing you can do to a gas engine.

And you'll be out an engine pretty damn quickly if it's running lean. There goes your MPG.

Huh, I had heard about that from a Jeep shop I used to take mine to back in Clearwater but never seriosuly considered it. How difficult was that change? Simple matter of pulling the rail and replacing the injectors, or did you have to remap or otherwise jigger with the electronics?

Our engines run leaner than ideal already to help meet emissions standards. Running even leaner should really be good on the valves and pistons.

100% bolt in swap.
Pull the electrical plugs off the injectors, pull the rail and the injectors just pull out.
The whole thing took me maybe an hour and a half and most of that time was spend cleaning the fuel rail and injector ports.
The set I have is flow matched so all injectors flow at the same rate and put out the same amount of fuel as the factory injectors. They just get it done more efficiently.
No computer reprogramming is required.

With the increased mileage I got from this swap, the injectors will pay for themselves within 6 months, then start paying me in the form of saved fuel.

I always want to give an honest review of these, 1 of my old injectors was fouled out and leaking, 2 more were suspect. I can't claim that these injectors are 100% responsible for the mileage increase because my baseline was so messed up. That increase may have happened because they are functioning correctly now and the rail is clean.

BUT, if I were in the same boat again looking to replace injectors, I would go this route without hesitation.
