Once installed, the Airsep had no noticeable affect on performance, but completely stopped our little oil leak at the front of the engine. We pressure-washed the Bomber's undercarriage, and now it stays clean and free of dirty grime. One added bonus of this system is that it actually draws a slightly negative pressure on the crankcase, which should help preserve gasket life. This is the finished product. Now we can hit the dusty trails of Baja without worrying about the Bomber's air intake.
