The new Turblown Cast Baffled 13BREW Oil Filler Neck replaces the failure-prone, plastic factory filler neck, with an internal baffle design + closed loop circuit which is proven to vastly reduce the amount of oil found in external catch cans.
The adjustable, o-ringed base allows 30 degrees of rotation and a superior seal whilst clearing the factory OEM throttle body, intake manifolds, Bosch DBW as well as aftermarket Turblown/Xcessive lower intake manifolds. The OEM thread pitch is retained for the filler cap, which while not included, can be replaced with one of our Billet Rotor Oil Caps.
The Turblown Oil Filler Neck also comes equipped with a -10AN ORB main vent and -6AN drain back port which is designed to connect via check valve to your catch can, with gravity drain. Hardware and o-ring included.
