Moose Blocks Injection Valley Breather, -12 AN

Moose Blocks Injection Valley Breather do all the same things as a crankcase breather but are just plumbed differently. These can be mainly used on dry sump motors and it does the job of 2 systems in one! It works as a vacuum regulator and a pop-off breather valve allowing consistent vacuum for more engine power.

• Mounts in the injection valley
• -12AN line runs to the dry sump tank
