Tomei Exhaust Manifold Gasket For Nissan RB25DET TA4060-NS06A

RB25DET engines in the R33 and R34 Skyline place significant stress on the exhaust manifold gaskets, often revealing the limitations of the original equipment design under increased boost and heat. The Tomei Exhaust Manifold Gasket (TA4060-NS06A) is a high-performance upgrade that uses a multi-layer steel construction with advanced embossed sealing beads and premium coatings to provide superior sealing strength and heat resistance. By targeting the known weak points of the factory gaskets, this set delivers reliable performance even under the extreme conditions common in tuned RB25 builds.

Tomei’s meticulous engineering ensures precise water and oil route sealing while the multiple thickness options allow builders to fine-tune compression ratios when combined with other Tomei components. The result is reduced risk of exhaust leaks, more consistent power delivery, and greater long-term reliability for both street and competition applications. This gasket set is an essential upgrade for anyone pushing their R33 or R34 RB25DET beyond stock power levels.

At Terra Firma Automotive, we supply this genuine Tomei Exhaust Manifold Gasket as a critical reliability component for serious RB25DET enthusiasts. Replacing the stock gaskets with Tomei’s advanced multi-layer design eliminates a common source of failure and gives you the confidence to run higher boost and more aggressive cam profiles. Whether you’re refreshing a daily driver or assembling a track car, these gaskets deliver the quality and performance expected from Tomei’s renowned engineering, helping your RB25 run stronger and more reliably for years to come.
