Cometic’s lower intake manifold gasket for the Nissan RB25 2.5L inline engine uses a chemically blown nitrile synthetic rubber bonded to an aluminum core. The AFM material offers about 85% recovery, strong torque retention and temperature resistance above 205°F. Cometic notes these gaskets do not require sealants or re‑torquing, providing a reliable, ready‑to‑install intake sealing solution for RB25 applications.
