Fel-Pro performance intake manifold gaskets are produced without a metal core so builders can trim them for exact fits on modified ports. Tested with many aftermarket head and intake combinations, they use Printoseal elastomeric sealing beads to reinforce sealing around ports. These gaskets are intended for performance applications and are not recommended for use in emission-controlled vehicles.
