Why? The plastic ones last 10 years if you dont let the valve cover leak oil onto them.I heard that Ford discontinued the metal housing that many upgraded to (F8RZ-8592-AG). Anyone aware of a replacement Ford part that's similar/better than the OEM SVT one?
I'm aware of the one that Massive sells, have one here, but was curious on the OEM solution that's also 1/2 the cost. Bostig also has one... at $500.
