We designed these to make it a little easier to service your engine with our blow by tubes. These simply snap in just like your original tube ends. The hole is based off a standard parts house funnel to hold into place. These have a 3/4" hole. No more valve cover removal to feed your engine!
Includes - 1 Oil Fill Adapter, 2 O-rings
All Parts Proudly Made in the U.S.A!!!
