Mazda Rotary Injector Bungs

Injector bungs set to block off injector ports in Mazda 12A & 13B centre plates and Mazda RX8 13B centre plates.

To fit, the injector bung body is inserted into the injector port and screw tightened to lock the bung in place. They are able to be removed at any time.

The two aluminium bodies are CNC machined from 6061 grade aluminium at our factory in Napier, New Zealand and then black anodised for corrosion protection and great looks.

Note - these bungs aren't compatible with FD 13B & 20B as the injector ports are a different shape

Supplied as a pair complete with Viton o-rings ready to install.
