Turbocharger gaskets create a gas-tight seal between the turbocharger housing and both the exhaust manifold and intake manifold, preventing exhaust gas leaks and maintaining boost pressure. These gaskets are constructed from materials like layered steel, copper, or reinforced fiber designed to withstand extreme temperatures and pressures. Specific gasket types include exhaust, intake, and turbo-to-coolant flange variants, each precisely matched to corresponding turbocharger and manifold surfaces. Proper installation, utilizing specified torque values, is critical for preventing performance loss and potential turbocharger failure. Variations exist to accommodate different turbocharger models and engine configurations, necessitating accurate part number verification.
