External Vent Kit Machined Finish

All Twin Cam and Milwaukee Eight engines have a crankcase breather system that routes over-pressure and eventually oil through the cylinder heads into the throttle body. That is with the stock air cleaner and almost any aftermarket and performance air cleaner. This kit allows you to route this pressure and the eventual oil into a separate cannister or breather filter. Kits include a pair of special breather bolts with washers and O-rings, as well as two adapters with 1/8" NPT barb fittings for use with common 5/16" hose. Hose, filter and cannister not included.
