Do I need any bolts or fasteners to install this?

This gasket seals between your header and manifold — you'll use your existing header bolts. Make sure those bolts are in good condition and torque them evenly after gasket installation to avoid warping.

Can I reuse my old gasket, or do I need to replace it?

Once you pull a header, replace the gasket. Old gaskets lose their seal integrity and won't compress properly the second time around. New aluminum gasket ensures a tight seal and prevents exhaust leaks down the road.

Does this gasket need any surface prep before installation?

Wipe both the header and manifold mating surfaces clean with a degreaser to remove carbon buildup and oil. Set the new gasket in dry and hand-tighten bolts first, then torque in a star pattern for even pressure.
