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

Am thinking about using Sea Foam Spray in my 2003 Chevy Silverado’s intake. Is it wise to change the plugs after a spray treatment?

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!
