This coil is intended for the Sprintmags and Super-Mag II, III and IV. Exactly the same as the 28900A red topped transformer, except not oil filled. This rugged coil is potted in epoxy for a long trouble-free life.

Utilizes the same rubber mounting foot the the other coils use, this is also a popular coil for use with Vertex OXC (external coil) magnetos to get maximum output and easy starting.

Comes with a terminal kit, boot and schematic.
