PROFILE

The ARM F3X Vent Port Plug is made for all 6-Speed manual transmission F-Series cars  to seal off the connection for the vent port on the charge pipe. 

Most aftermarket charge pipe upgrades, like the ARM N55 Charge Pipe, include a vent port for AT cars and include a plastic cap to close it off if you have a 6MT car.  These caps are typically not very reliable and will leak or pop off under boost, leaving you with a CEL and the car in limp mode . 

The ARM Vent Port Plug provides a secure seal for this unused connection. 

CONSTRUCTION

The ARM Vent Port Plug is machined from a solid piece of aluminum and comes with a  high-temperature O-ring to provide a tight seal at the vent port connection on the charge pipe.

It is secured with one 2.5mm hex screw to lock it in place.
