4 ohm 12 volt dual output universal ignition coil. This coil fits many different twins (that require 1 dual output coil) and four cylinder bikes that require 2 dual output coils. It's a replica of a Suzuki ignition coil but the mounting hole spacing is quite universal. Bolts right up on some Honda twins, Kawasaki's & Suzuki's.

Check the coil mount spacing on your bike before you order.

Sold individually. You'll need two of these for a 4-cylinder bike, one for a 2 cylinder bike.

Dimensions:

Mounting holes are 90mm (3.5") apart center to center.
Overall distance to the end of the mounts = 104mm (4.1")
Low tension wires (black and yellow) 390mm (15") long.
Female spade connectors at the coil and 1 male bullet / 1 female bullet terminal at the other end
Spark plug wires (high tension leads) 570mm (24") long with 300mm (12") protective sheath.

Great Replacement

Posted by Mike Baker on 17th Apr 2020

Great replacement for OEM coils. This is my second purchase for these coils. I used for 4 different Suzuki models, 4 stroke and 2 stroke with excellent results.

Always good parts; always on time. (Coil for a '77 kawasaki kz400) works excellent.

Good quality replacement

I'm using this for a Suzuki GT550 application. Using 2 dual 4.0 Ohm coils with after market electronic ignition. Better performance is achieved by using two coils rather than 3 singles and just grounding the "extra" spark plug lead
