X2 just remember after seafoam normally you'll want to change your plugs

Also put some seafoam in the gas tank and change the filter first.

umm. Guys, think. How exactly is seafoam through the intake manifold going to go through the fuel injectors??? That will clean the intake manifold, valvetrain, and cylinders. In order to clean the fuel injectors, you would need to put it in the fuel tank.

I thought he said engine cleaner... all the detergent based fuel injector cleaners are pretty much the same, I use Lucas upper cylinder lubricant with fuel injector cleaner every couple months.

I use gum out. shit works.

Why would you change thefuel filter before you add sea foam to the fuel?
