I hate to say it but the Spitfire plugs are just a gimmick. They have been around for years, in the 60s they were marketed by JC Whitney under a different name. Take a look at the the Feds complaint filed against them:

Yep I've seen them too, but JCW did sell a fork tongued spark plug too! Oh well we all get had once in awhile. I remember putting water injection in my old '63 Dodge truck. Several of the guys at work bought these kits and installed them on their cars and were bragging about them. I though it was BS but copied their $20 systems with about $2 worth of aquarium tubing, an aquarium air needle valve and a plastic jug. Set the thing up using the directions from the kits the guys had. Of course with careful measuring of mileage and 1/4 mile time before and after there was no change in performance or fuel burn. The system used less than a fraction of an ounce per mile, couldn't have done much. The other guys continued to swear by thier units but I noticed some months later they didn't have them on any more.

For me it all goes back to the idea that if these gimmicks actually worked they would be bought up by the vehicle manufacturers and put in their products. Every maker is looking for an edge to make their cars, bikes or whatever better than the competition so it's unlikely they would pass up the possibility to improve their product with such a simple addition. Any piece of junk they have to sell with puffed up ads in magazines and "as seen on TV" type sales has got to be such a small operation that Ford or GM could buy them out with pocket change if they wanted to or they'd find a legal way to get around a patent and add it to their vehicles. After all, how long did it take for all automakers to find a way to get around the patent on the electric starter?

exavid, actually water injection works quite well. High performance aircraft, even tractors of the 30's & 40's used it. We have come close to releasing it for production on low production automobiles a couple of times.

BUT, just adding water to the intake doesn't add much by itself, itallows other improvements to add up to a power gain.

When you added that water system to your car (or truck) if you would have leaned the carb slightly at light load cruise & bumped the mid range ign timing up a couple of degrees you would have seen a slight mileage improvement.

Yep I've seen it on an aircraft engine and know the history of water injection. The point I was making was that it was sold to a lot of folks in the early 1970s as a gimmick. If you are adding the water to a vacuum port in the intake manifold with no control on the flow other than a fixed setting needle valve, with no adjustments whatsoever to the rest of the fuel and ignition systems, not to mention the fact that these things used such a tiny amount of water it couldn't have had as much effect as driving on a foggy day. Those particular systems were about as effective as sticking magnets on your fuel line.
