Most Fel-Pro Performance intake manifold gaskets have Printoseal construction, which puts beads of special elastomers around the ports for extra sealing power. They also feature a non-metallic, rubber-fiber base material that resists gasoline and alcohol—and they allow engine builders to precision-trim around the intake ports. These replacement gaskets are available in a variety of materials, thicknesses, and port configurations. Order the set recommended for your vehicle year/make and engine application.
