They do work sort-of. You would be far better of getting the "correct plug" and keeping the engine tuned properly. A clean running engine will not foul plugs and is easily started.
If your plugs are fouling they are trying to tell you something but only if you listen.
In running my ole A-4 (34 years) I never cleaned a plug and only had to dry a few when dewatering. I used my plugs for at least 3 seasons and did have an EI.
Plugs do break down as far as electrical resistance is concerned and that can't be cleaned!

oh I agree with you 100% I just see these things and sometimes wonder...
new plugs for this year are waiting to go, but I do need to solve the too rich setting on the engine this spring (pulled the plugs in the fall and they were black! - I fee so ashamed)
My first cruising (overnight) boat had an outboard, and I recall toasting spark plugs on the alcohol stove. That engine was stolen - thief deserved it!
With the A4, if you're running rich I'd suggest the adjustable main jet offered by our host. I like this adjustable jet and have installed it on every engine I've owned or overhauled.
