Part# ASxxxx - AussieSpeed sand cast alloy wiring port base is designed to be use with all of our AussieSpeed oil breather caps.  Mount this base to the firewall and the wires can come in through the middle then just slot the oil breather cap to which side you want the wires to exit.  Drill the Oil brether cap for the mounting grub screws so you can locate them in a position where you can get a tool in to tighten up the screws.  Supplying them like this makes it a much better job, you can tailor them to suit thier location on the engine bay firewall.

This is for the base only - order oil breather caps separate
