Photo galleries of factory original 911R Magnesium Intake Manifolds

These parts now belong to collectible 911 Porsche vintage racing cars. The 911R Magnesium Manifolds are getting even more difficult to find and over the years they have become astronomically expensive. When purchasing these rare parts, be careful and be sure to inspect them. Some of these Magnesium manifolds have sustained damage showing hairline cracks at the bottom-flanges. The bottom flange normally cracks and brakes off as nuts are over-tighten over an uneven surface. Use a straight-edge to check that all the heads are on an even plane.
