Ford ST170 Duratec Manifold Flange

Ford ST170 Head Flange, laser cut from 8mm 304 Stainless Steel. We use these on all our race car and rally car builds. We can also supply pressed steel transitions in either 304 or 321. The 321 although more expensive offers the ultimate in terms of strength and longevity. Please note, the pictures show the flange with transitions, if you want these choose either 304 or 321 from the options list below! For turbo, race and rally applications the 321 is highly recommended.
