1983 thru 2004 “Mondo” High Output KX500 Ignition Coil


The MSV Racing ’83-’04 KX500 “Mondo” High Output Ignition Coil is the modern high-performance upgrade to your OEM KX500 ignition coil.

After testing 5 different ignition coils, we finally found an upgraded ignition coil that we feel is worthy of the savage KX500.

Our coil provides a 30% stronger spark than the OEM coil. This stronger spark can aid in starting, crispen up jetting, provide better throttle response, and offer more torque and horsepower by burning the A/F mix in your combustion chamber more efficiently.

Not only is this a better coil, but it is also cheaper than the OEM KX500 Coil too.
