The MBE9A8 has four ignition drives, that can be fired either sequentially or in wasted spark mode, depending on requirements & set-up. The normal MBE9A8 has built in amplifiers so there is no need for expensive external units. You can use four individual coils (such as used on the Suzuki hayabusa) or twin coil pack (GM, Peugeot:COIL-4 or Ford:COIL-9).

When being used on a 6 cylinder engine, you can use a wasted spark coil pack from many of the production cars eg. GM. If you are using an 8 cylinder engine, you could use a pair of the 4-cylinder coil packs.

NOTE: If you would like to use coil-on-plug on a 6 or 8 cylinder engine you would need to order a special MBE9A8 to run external amplifiers, which would then allow you to run the coils in pairs.

If you have coils with built-in amplifiers, an MBE9A8 can be built to order.
