Seafoam DIY- Do spark plugs HAVE to be replaced?????????
 

I want to seafoam my car, but do the spark plugs HAVE to be replaced after doing it?
I know its recommended and i know why but i just changed my plugs about 1,500 miles ago and would hate to have to change them when they are brand new. Please help as i am wanting to do this TODAY if possible. Thanks fellas
