Polaris 120 Power Intake Kit

Our kits include a special preload and rate governor spring to let the 120 rev higher without damaging its plastic governor like solid wires can do. The new style spring will also give you a smoother idle without surging, like running with the governor unhooked will cause. Next we developed and flowbench tested a new velocity stack that will let your engine have better throttle response and top end RPMs. To top off the POWER INTAKE KITS, we built an Adjustable Main Jet so you can set your carb for peak performance at any temp. The best performance gain is achieved when you use our complete kit, but parts can be purchased separately.
