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.
