What is the purpose of the vent in this oil fill cap?

The vent prevents pressure from building up in the oil system. This is especially important in high-performance engines or those with aftermarket modifications, where crankcase pressure can be higher than stock.

What size wrench do I need to install this?

Refer to the manufacturer's installation instructions for details. AN fittings typically require flare nut wrenches to avoid rounding off the corners.

What other parts do I need to install this?

This cap adapts -10AN ORB female to -20AN male. You will need to source the appropriate lines and fittings to complete your desired setup. Ensure all components are compatible with your vehicle and oil system.
