Never done it, but got 2 cans ready. The question is: since i got a set of new spark plugs, should I do the sea foam and then plugs or plugs then foam?
Thanks

 

Foam then plugs

 

Seaform before spark plugs!

 

i concur. just like seafoam before oil change.

 

seafoam, then oil and filter, then plugs.

 

I think it depends. If things are pretty mucked up, Seafoam then plugs. I have a 90 Bronco that was mucked up pretty good, had been a while since plugs changed. I shanged them then seafoamed and had to change plugs again 2 months later.
