AELLA Crankcase Breather for Ducati 848/1098/1198 and Multistrada 1200 (Internal Pressure Control Valve Evo 2)

For peak performance, it is VERY important to Optimize the pressure state inside the crankcase and airbox!

Keep the crankcase internal pressure proper by merely installing our high tech AELLA Crankcase breather. Our EVO 2 internal pressure control valve relieves excessive engine braking. This helps to eliminate the rear wheel lock at the time of entering the corner and the acceleration from the apex, to realize a smoother running bike.

AELLA's Evo 2 Crankcase breathers are especially effective with the Ducati L-twin engine, which shares one crankcase because the compression resistance inside the case is very strong due to the structure's shape.

Resistance decreases with wearing, idle rotation may increase by 200 to 500 rpm in some cases. Just by installing, it quickly changes to a smooth and torqueful feeling over the whole area. Please experience the change as if you tuned the engine with your own car. Fuel economy usually increases as well, since engine resistance is decreased.

We recommend cleaning cleaning every time the engine oil is exchanged.

The breather tower type demonstrates the maximum effect with crankcase direct connection, but at the same time it increases the amount of oil mist attached at the same time. When oil mist adheres to the valve, it inhibits the movement of the valve, which in the worst case causes the valve to stick. We will restore the original state just by cleaning the interior of this product with a parts cleaner, so we recommend cleaning every oil change.
