Good To Know

Q: Will this cap fit my Trail Boss 350? A: It is listed for Polaris Trail Boss 350 models from 1990 through 1993, so confirm your exact model year and serial number before ordering.

Q: Do I need to replace the ignition wire too? A: Usually no, but if the wire end is frayed or the boot does not seat firmly, trimming or replacing the wire may be needed for a solid connection.
