The Golden Eagle Mfg plug inserts directly into the large open hole left behind when you completely delete the restrictive OEM PCV "Black Box" from the back of the block. The plug uses dual O-rings to create a tight, leak-free seal without welding.
Once this factory breather box is deleted and plugged, the crankcase pressure is safely redirected out through those two largeM28 ports into your high-flow aftermarket catch can system.
Includes:
(1) Breather Box Plug (Black or Polished)
(2) M28 to -10AN adapter fittings
(2) Honda 90401-PR4-000 Washers
