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 -AN 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.
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. We recommend the ThreeBond Gasket Maker.
