OMC's part #582365 is for a "you cut to fit" plug wire kit.  You cut your length, install the spring terminals & boots and hope you get it right.  My 582365-9" C plug wire is completely assembled for you to install.  Made from solid tinned copper core 7mm wire.  Crimped snap lock terminals, they are the best.  Terminals are coated with dielectric grease for corrosion protection and maximum spark.  This is a 9" wire, used on OMC'S with 582508 coils.  Some V4 motors require a longer wire, so check the length of your wire. Price is for a set of (4) 9" wires as shown.
