These Solinoids were purchased at Gordies in the summer brand new. I have used it around 5-6 times so the are relativley new. $325 will get you the kit and ONE bottle. $400 will buy the kit including 2 bottles. Cant go wrong with these bigger solinoids either. They spray more than the little ones. The reason i am selling it is to buy a direct wet kit. I currently have it installed in my Cherokee now so if youd like to try it out we can.
