- Reduced vibration and smooth torque transfer (three pulses per revolution instead of one)
- Improved muffling performance by spreading exhaust pulses in time
- Improved power and SFC from three-into-one cross-stuffing exhaust
- Ideal for spark ignited heavy fuel due to small cylinder bores and liquid cooling
- Based on the proven combustion system from the A33
