What is the purpose of a vented oil fill cap?

A vented oil fill cap allows excess crankcase pressure to escape, which is especially important when running a high-performance engine or forced induction. This helps to prevent oil leaks and ensures proper engine operation.

What size is the thread?

This Granatelli oil fill cap features a -10AN ORB (O-Ring Boss) female thread. This is a common size for connecting to aftermarket catch can or breather systems.

Is any special installation hardware required?

No, this oil fill cap is a direct replacement for the factory cap. Simply remove the old cap and screw this one in by hand. Do not overtighten.
