Techron Fuel system cleaner
Techron concentrate has a good rep in the enthusiast world. I've been using it for quite some time with many different vehicles. Since I use high quality gasoline (a virtual must with an Evo), I only use a bottle about every 5000+ miles...

It used to be recomended in BMW and Porche owners manuals every 2-3k miles. I've been using it for over 13 years and have never had a problem with clogged fuel injectors or anything else. The only catch is that it is more expensive than most of the others on the market but in my opinion well worth it.
