Do I need bolts to mount this gasket?

Bolts are not included with this gasket. You'll use your existing fasteners or sourced hardware that fits the 2-bolt pattern. Torque spec depends on your specific application — check your engine manual or intake manufacturer guidance.

Should I use gasket sealer or sealant with this?

Aluminum gaskets typically work fine dry on clean, flat surfaces. If you're working with older or rougher flanges, a thin bead of gasket maker on the flange surfaces before installation can improve the seal. Test-fit first to confirm surface contact.

Can this gasket be reused after removal?

Single-use is recommended. Once compressed and seated, aluminum gaskets lose their spring and seal integrity if disturbed. Plan to replace it if you disassemble the joint again.
