This is a fully recirculating blow off valve. A quiet alternative to the atmospheric BOV, the Plumb Back systems vents all excess pressure back into the intake system. Ideal for cars with sensitive Air-Flow systems and off-road applications as the fully-sealed design of the Plumb Back prevents any foreign matter entering the system. Comes with a weld-on flange.
NOTE: If you are mounting this on a steel intake tube you will need to purchase a steel weld-on adapter, see Part #: 1072011.
