Brand new PROK Series Tornado air filter assembly.
It fits many styles of Keihin or Mikuni SBN 34, 38, 40, 44, 46 and 48 carbs when using the correct adapters, which are also listed.
This filter provides a nice increase in fuel/air flow mixture, resulting in a nice, clean, crisp throttle response.
These measure 4″ round and 2 1/4″ tall. The I.D. of the coupler is 71mm or about 2 3/4″.
