So after using seafoam my car feels pretty good now. After traveling about 50 miles after sucking 1/3 of seafoam through my break boosters and dumping the rest in my full gas tank of premium shell gas I didn't notice too much of a difference but once I changed my oil (oil was dark black with minimal gunk and put in some gastrol gtx 5w-30 it feels almost better than the day I got her. Very good product right here gentlemen. Oh yeah I have a 4th gen so there's that.

Seafoam is a great product, especially does the job well introducing into the intake induction will definitely break up the carbon build up for those who have neglected to do regular interval oil changes and some injector cleaner. Will see a lot of black smoke, but if you get a lot of white smoke, pretty much it's clean. I did that once, thought for added measure, it just smoked white, pretty clean since I do change my oil regularly.
