The kit contains three brass coat steel wire brushes for cleaning the carbon deposits from the inner side walls of the port and two silicone nylon brushes for cleaning the base /injection seat area. The silicone nylon brush is required on the base/injection seat area as this type of brush gives a smooth and consistent finish to an aluminum surface, particularly important on this sealing surface.
