I did some research, and everywhere i look i read that I should change the spark plugs after I run seafoam through the intake.
Is there truth to this? If there is then F it. I'm not risking a blow out, I hate doing plugs on the 4.6 because it always makes me paranoid

They most likely recommend this because there is a possibility of fowling a plug. If it still has spark on all cylinders after doing the sea foam, then don't worry about it.

isnt it possible that carbon deposits could still allow the plug to fire but weaken it's spark?

To sorta quote "MrVax" (one of our mods) , those in the know do not use seafoam - it's OK to recommend it to others.

LOL !

I hate changing the plugs especially since I am a victim of shoting a spark plug out of the head. I wouldn't use that stuff if you need to change the plugs. Leave it alone.

So TripleBlk why don't you explain why "those in the know" will not use it?

because it is a complete waste of time and money... Probably won't hurt so long as you keep it off the mass air sensor, etc. But it won't help a thing. Find a 4-cycle lawn mower, pull the head and look at top of piston, valves, head, combustion chamber, etc. Run sea-foam through it. Pull the head again. Looks the same or worse, eh?

On a rebuild, take a badly carbonized piston and try to clean it. It is a royal pain, and there is literally nothing you can just "soak" the thing in (that is legal to buy / use) that will dissolve that carbon mess. Including seafoam. It has its uses to be sure. But this just isn't one of them that is any good.

Yea, I agree with the above. I just use it for the smoke show to be honest, there can't possibly be anything that it cleans
