The plastic material used in the construction of the intake manifold is the main source of the problem. Over time this less robust plastic material cannot withstand the constant heat cycles and mechanical stresses, therefore embittering and weakening the material leading to inevitable failure. Our Premium intake manifold repair kit is the only solution which solves all of these issues during your first and only repair. 2 x Engine Intake Manifold Gaskets 1 x Intake Manifold Air Flap Lever
