STM Valve Cover Fittings for Evo 4/5/6/7/8/9

Always looking for ways to make the engine bay cleaner, lighter and easier to work with, the STM Aluminum Valve Cover Fittings allow you to simply install lines and fittings for a catchcan or breather right onto your Evo 4/5/6 or 7/8/9 valve cover. Please review all fitment notes below. (Here) Install Notes: The fitting itself is a very tight fit, but we would definitely recommend a touch of glue or epoxy to help hold it in place in the valve cover upon install.
