STM -10AN REAR VALVE COVER FITTING (EVO VIII-IX)
STM revamped our valve cover fitting to allow a true -10AN rear fitting for a serious catchcan set-up. Simply remove the hot mess you are running now and cleanly install this simple, yet brilliant, little fitting.
As the piece itself is a very tight fit, we would definitely recommend a bit of glue or epoxy to help hold it in place in the valve cover upon install.
Retails for $35, and we have them on our Tax Season Sale now for $30 HERE!
