Cometic intake manifold gasket for Nissan RB20E/DE/DET uses AFM material with a .032-inch thickness to seal the intake manifold to the head. AFM offers high recovery, strong torque retention and temperature resistance over 205°F, and the gasket does not require sealants or re-torquing. It’s specified for RB20 applications and intended to provide reliable intake sealing in stock and mildly modified engines.
