Cometic 4-Cycle Head Gasket .018" MLS Fits Yamaha YZF-R1 2004-2006

The Cometic 4-Cycle Head Gasket Kit is engineered for maximum performance, durability, and reliability. Designed with advanced materials, it incorporates Multi-Layer Steel (MLS) technology for even torque distribution, reduced bore distortion, and superior piston ring sealing for enhanced power. The stainless steel outer layers are embossed and coated with Viton, a heat-resistant fluoropolymer rubber capable of withstanding temperatures up to 482°F (250°C). This coating ensures exceptional performance under harsh sealing conditions, varying load demands, and diverse surface finishes. The central shim layer, made of uncoated stainless steel, allows for customizable thickness to suit specific requirements. This gasket design is ideal for use with aluminum heads on aluminum or cast iron blocks, effectively handling the shearing forces between the materials. Cometic's gaskets are crafted from premium fuel-resistant materials that resist cracking, creeping, or becoming brittle over time, making them a reliable choice for high-performance applications. This kit offers a robust, long-lasting seal, catering to the rigorous demands of modern engines.
