MADE IN U.S.A
**THIS WILL PREVENT SUPERCHARGER FAILURE!**
(Your supercharger should be fogged after every use to prevent buildup and corrosion on the supercharger internals, which ultimately causes loss of power and eventually a blown charger. Here at Kawi Performance we have an aftermarket kit that will allow you to easily fog your supercharger while you are flushing the engine. We recommend installing the port just above the seat bracket. Made of completely rugged Stainless steel and PTFE. When you are ready to fog, the cap screws off and is attached by a chain to prevent it falling into the water. This kit requires some basic hole drilling and tapping for threads on supercharger intake duct. If you rather us tap the hole in your intake duct, we would provide this service for free with purchase of a kit. Comes with clear installation instructions with pictures!)

Both of the KP pulleys below are much lighter than stock, thus reducing belt wear and spool time. They are slightly bigger than stock as well, which puts more even pressure on the belt for even more extended life. Stainless bearing comes standard with the SS pulley, the steel pulley comes with steel unless you would like ss.)
