STM Valve Cover Fittings - Evo X

STM Tuned Inc.


Vehicle Fitment:
2008-2015 Mitsubishi Lancer Evolution X
• Confirm compatibility below with plastic or metal valve covers.

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 valve cover.

The -10AN Front Fitting removes the PCV Valve and re-uses the factory O-ring. For track & racing use only. Not intended for public roads.

-6AN Side Fitting:
Fits metal valve covers only.

-10AN Front Fitting (
PCV Valve Replacement):
Fits both metal and plastic valve covers.
For racing use only.

STM Products are made in the USA!
Lifetime Warranty on STM Parts to the original purchaser against manufacturing defects.

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.
