Tomei Exhaust Manifold Gasket For Nissan RB25DET TA4060-NS06A

High-boost and high-temperature conditions on the Nissan RB25DET place significant stress on the exhaust manifold gasket, where factory designs often become a weak point. The Tomei Exhaust Manifold Gasket (part number TA4060-NS06A) is a multi-layer steel upgrade specifically engineered for RB25DET engines, including NEO6 variants, as well as compatible RB20DET applications. Constructed as a three-layer metal gasket with a 0.75 mm thickness and bead-type sealing surfaces, it delivers improved resistance to heat, pressure, and exhaust gas leakage compared to the original equipment gasket.

Tomei developed this gasket after analyzing the failure points of stock units under sustained high-load operation. The embossed bead design concentrates sealing force where it is needed most, helping maintain a reliable seal even as the manifold expands and contracts with temperature changes. This makes it a practical choice for both street-driven and track-focused RB25 builds that see elevated boost levels or aggressive tuning.

At Terra Firma Automotive, we supply this genuine Tomei Exhaust Manifold Gasket as a critical reliability component for Nissan Skyline R33 and R34 owners, Stagea models, and other RB25-powered platforms. Whether you are refreshing a manifold during an exhaust upgrade, addressing an existing leak, or building a higher-output engine, this multi-layer steel gasket provides the durability and sealing performance expected from Tomei’s Japanese engineering. Install it with confidence knowing you are using a purpose-built solution designed to handle the demands of modern performance RB engines.
