Here is a Thunder Mfg performance air filter kit for a Kawasaki Vulcan 1500 Classic (Carbureted Models Only).
The years it fits is UNKNOWN.

This kit most likely sold for over $500.00.

This kit is New Old Stock sitting on a shelf for many years.  There was no parts list in the box it came in so I don't know if all the parts/hardware are there.

Please review the pictures and ask any questions before buying because it is being sold AS-IS. No Returns.
