Intake and exhaust header pipes helps a little. But in general all of those after market “save gas” gadgets are scams. Popular science tested many of them and they all HURT mpg.
There are few thing you can do to save (or maximize) gas MPG. First get a tune-up.
(1) spark plugs
(2) spark plug wires
(3) distributors, coil, rotors (if you have them).
(4) new air filter
(5) PCV
(6) correct tire pressure
(7) clear the trunk of useless heavy items
(8) spray clean MAF sensor.

Forget all those “SAVE GAS” scams. This was on NBC morning TV show. The difference is as much as 38% (their claim). There are very simple rules to save gas:
(1) drive slow – not too much past 55
(2) accelerate slowly
(3) don’t brake unnecessarily
(4) use cruise control – whenever it is safe to do so.
Don’t coast – it is NOT safe (to coast in Nuetral) and it does NOT save gas. It only saves gas, if you are planning to slow down (exiting, tolls, traffic). Coasting then accelerating again is LESS efficient than just cruising.
The above really works. Using those simple rules I was able to drive from Boston to NYC (210.5 miles) on just 5.112 gallon (94 Civic). That’s 41 MPG (94 Civic 187K miles). Actually I was speeding at 72 MPH so I could do even better at 55.
WOW !!
Good Luck….
If there were such an additive, it would be all over the news. The first poster is right, check your tire pressure and do the speed limit. I add a few extra pounds of air to each of my tires to limit the amount of contact my tires make with the road. But do not over inflate, or your tires will not work well on wet roads and braking characteristics will be terrible. Also, it can cause tire failure while driving, causing an accident and then you won’t have to worry about better gas mileage.
Accelerating slowly and doing the speed limit, or even slower dramatically improves gas mileage. It may seem slow driving 55, but even the people behind you will know that you are driving slowly to save gas. Just stay out of the fast lanes.
