Cometic Nissan RB25 2.5L Lower Intake Manifold Gasket Precision Seal for RB25DET Engines
The Cometic Nissan RB25 2.5L Lower Intake Manifold Gasket is engineered for seamless integration with high-performance RB25DET setups in Nissan Skyline models. This gasket delivers consistent vacuum retention and heat resistance in demanding conditions, ensuring your inline-six runs without interruptions from manifold leaks. Built with advanced materials that handle extreme engine bay temperatures and pressures, it stands as the reliable option for enthusiasts rebuilding or upgrading RB25 engines, preventing common issues like air leaks that plague lesser alternatives.
Why This Gasket Fits Your Build
The IR511060AFM uses Aluminum Foamette (AFM) construction an aluminum core bonded to a compounded nitrile synthetic rubber layer with an 85% blow rate for enhanced conformability and recovery. This design maintains bolt torque while sealing irregular surfaces, offering longer service life compared to traditional paper or multi-layer steel gaskets. It withstands temperatures exceeding 250°F, making it suitable for turbocharged applications where stock gaskets often fail prematurely.
