A question about Sea Foam Spray and spark plugs [SOLVED]

Thanks for the question, James.  There is no need to remove spark plugs or do anything else after using Sea Foam Spray.  I think people get this idea when they foul a plug because they forgot to warm up the engine to operating temp or elevate the engine RPM during application. Just make sure you warm up the engine and you’re running steady between 1,500 and 2,000 RPM while applying the spray into the throttle body. Hope this helps!

Which product are you all using for this? I just used the one that goes into your fuel tank, will it do the same thing?

They’re using Sea Foam Spray. It’s different from the one that goes in your gas tank (which would be Sea Foam Motor Treatment in the red can or Sea Foam High Mileage in the black and silver can).

Sea Foam Motor Treatment in the gas tank will clean fuel residues and deposits anywhere the gas goes. Those residues and deposits are often the cause of many common engine problems like rough idle, loss of power, and poor fuel efficiency. It’s the most popular Sea Foam product by a lot.

Sea Foam Spray is an aerosol version of Sea Foam Motor Treatment. Sea Foam Spray is more specialized for use in gasoline engine intakes and particularly effective for cleaning intake valves where a fuel treatment like Sea Foam Motor Treatment can’t reach.

Hope that helps! If you have a particular problem you’re trying to solve, let me know and I’d be happy to help with the best product.
