NOTE- Aftermarket ONAN "B" Style coils are not currently available. We had only found one quality viable option for these coil that are 100 percent correct speced. BUT we do have this  aftermarket coil option that will work, and is our only option for this part besides our Onan OEM coil listing. This Aftermarket coil we are offering here will get you up and back running. 
 
There are options to Add New Spark plug wires and Spark Plugs To Your Order.
 
OPTION- For coil bracket to accept newer style coils like this
 
OPTION- To add recommended new high quality spark plug wires
 
NOTE: Some early model Onans may require a separate bracket/hole modification to mount this style coil. If your tractor still has the complete LONG cylinder looking coil that is completely circular from top to bottom long and skinny, then you will likely need an adapter bracket or hole modification Also note that all new replacement coils for Onans are non threaded for spark plug wires. We recommend replacing your wires if you do have threaded wires boot ends, and it is also a good practice to swap them out when you change the coil anyway. There is an option at check out to add wires to your coil order.
