A proper seal at both the intake manifold and the individual throttle bodies is essential for consistent performance on the Nissan RB26DETT. Over time, the factory gaskets can harden, distort, or develop leaks that affect idle quality, throttle response, and mixture control. This Tomei kit combines two critical components—the Intake Manifold Gasket (TA4050-NS05A) and the Throttle Body Gasket Set (TA4030-NS05A)—to provide a complete sealing solution for the upper intake system on Skyline GT-R R32, R33, and R34 models.
The intake manifold gasket features a steel bead-type design that improves clamping force and heat resistance compared with the original equipment. The matching throttle body gasket set includes six individual steel gaskets with a fluorine coating, one for each throttle body. Together they restore a reliable seal across the entire intake tract, helping prevent vacuum or boost leaks that can develop after years of heat cycling or during intake service.
At Terra Firma Automotive, we supply this genuine Tomei combination as a practical upgrade for RB26 owners performing intake cleaning, throttle body work, or engine refreshes. Whether you are maintaining a street-driven GT-R or supporting a higher-output build, these precision gaskets deliver the fitment and durability expected from Tomei. Choose Terra Firma Automotive for authentic Japanese components that keep your RB26 intake system properly sealed.
