Application: Porsche® 928 1978-1984 all with 16-valve motors
Improved Exhaust Flange Fasteners: Get rid of those old, rusty exhaust flange nuts and the washers that go with them! (The washers are a pain when you try to install/re-install your headers). Our nuts are flanged so the old washer is unnecessary.
ALSO: These nuts have a serrated flange so they go on easy, but will not loosen by themselves.
Made from Grade 8.8 alloy steel and black finished as shown.
