This heater plate is the same diameter and thickness as the plates in our KS90 and KS90R engines and has the same pattern of screw holes. It can either be fitted as a direct replacement or simply placed under the existing bottom plate.
This heater plate is compatible with all current and earlier KS90, KS90R, and KS90V aluminium, acrylic and copper engines.
It runs from any normal USB port that provides 1 amp. Just wait 2 to 3 minutes after plugging in and start your engine.
