Q & A

What's in the Box

Screw into the oil drain back holes above the camshaft and benefit in 2 ways; First, they allow crankcase pressure to vent upward without having to fight the oil trying to drain into the pan. Second, they keep the oil from draining directly onto the cam causing windage and power loss.
