YOU HAVE FIVE POWER PERFORMANCE OPTIONS

  • Option 1: American made high performance Uni-Filter air filter ensures clean air to your engine and long life.  See why a NEW Uni-Filter is MANDATORY for ALL new engines and purchase at this link.   Your one year new engine warranty applies only if a new uni-filter is purchased with this engine.  If you don't get a Uni-Filter you are guaranteed to be putting dirt into your clean NEW engine.  Stock air filters do not effectively filter air and are the number one engine killer for GY6 engines.  Don't get an engine without one.  See Details
