The most common setup configurations are between the engine crankcase & intake manifold or between air intake & engine crankcase, or both. The box contains mounts and hoses; since this is catch can is designed for universal fitment and configurations could vary depends on actual usage, users could expect to source for hoses longer in length or customized mountings.
