Air/Oil Separator H/D 88-16 EVO Twin-Cam

The Air/Oil Separator H/D 88-16 EVO Twin-Cam by MOROSO is an essential upgrade for serious Harley-Davidson enthusiasts running aftermarket breathing modifications or high-performance tuning. This separator is specifically designed for the EVO and Twin-Cam powerplants, addressing excessive crankcase pressure and oil vapor recirculation that can degrade engine efficiency and reliability.

Utilizing centrifugal oil/air separation technology, this unit effectively extracts oil mist and vapor from crankcase ventilation gases before they enter the intake tract. The separator spins incoming vapors at high velocity, forcing heavier oil particles to the outer chamber walls where gravity directs them back into the engine, while clean air returns to the induction system. Its compact dimensions of 6 x 5 x 9 inches and lightweight construction of 2.1 lbs facilitate straightforward installation in tight engine bays.

Street riders, drag racers, and touring enthusiasts will find significant benefits from this separator, especially those utilizing carburetor or fuel-injection systems sensitive to oil contamination. Whether you're running a Stage II engine kit, turbocharger setup, or simply pushing higher boost levels, this separator is crucial for protecting your investment and ensuring optimal engine performance.
