The HKS Head Gasket for the RB26DETT engine, designed with an 88mm bore and 1.2mm thickness, delivers outstanding reliability and cooling performance for high-output builds. Utilizing a grommet type structure, this gasket ensures superior sealing strength and prevents failure under extreme pressure and heat, making it an essential upgrade for Nissan Skyline GT-R owners pushing their engines on the street, track, or circuit.
What sets this gasket apart is its specialized cooling capability. By widening the water passage holes, HKS engineered this gasket to allow more coolant flow through the cylinder head, effectively reducing hot spots and balancing temperatures between cylinders. This advancement not only improves overall durability but also raises the knock ignition limit, providing more headroom for higher horsepower applications. In-house testing has shown a significant reduction in temperature variation, further solidifying its role as a critical performance component.
Paired with strengthened head bolts such as ARP, the sealing effect becomes even more robust, ensuring maximum efficiency in high boost and demanding driving conditions. The gasket kit also includes exhaust manifold gaskets, an intake manifold gasket, and throttle body gaskets, offering a complete solution for installation and long-term dependability. Terra Firma Automotive supplies this premium HKS component to ensure your RB26DETT build receives the precision and strength it needs to perform at its peak.
