STM Rear Valve Cover Fitting -10AN | 2003-2006 Mitsubishi Lancer Evolution 8/9 (EVO-VCF-10R)
STM revamped their valve cover fitting to allow a true -10AN rear fitting for a serious catch can 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, they definitely recommend a bit of glue or epoxy to help hold it in place in the valve cover upon install.
