I actually own one of the water injection companies, One of my friends refered me to this site to pass the info on. There are however 3 or 4 other major makers of these kits and you can feel free to check out them all.

The results will be pretty much the same on any kit by any kit maker it's just about how much you want to pay for your system and how you like the individual set up.

Carbon does not hold any benefits in the modern internal combustion engine.

Carbon build-up on top of the piston or on the cylinder walls may also cause preignition. This would give similar results to the cooling system issue. The carbon buildup could be because of running extremely rich for any length of time. Therefore, when repairing high CO emissions failures, always assume that carbon has formed. Oil consumption will also cause this type of carbon, which will also cool the combustion chamber temperature. Carbon on the throat of the valve will absorb fuel, causing a lean condition and giving a similar result as to the previous lean condition.

It will also build up on valve seats as well, The exhaust valve-seating surface is not just to seal the cylinder airtight, but to provide a means of removing heat from the valve and disbursing it to the cooling system. An incorrectly seated exhaust valve will not transfer heat. Consequently, the valve and its seat will rise in temperature, causing preignition. This will result in high HC, high O2, low CO, low CO2, and high NOx.

There's a whole laundry list of stuff caused by carbon and soot build up, eliminating that means leas engine wear no matter how you look at it
