The Cometic Gasket Honda Civic 1.7L D17 MLS Head Gasket (Part C4474-027) is engineered for high-performance engine sealing. Comprised of multiple embossed layers of stainless steel with outer layers coated in Viton rubber, this gasket offers exceptional durability and resistance to harsh conditions. The compressed operating thickness of 0.027 inches ensures a reliable seal for demanding applications. Designed to fit Honda Civics from 2001 to 2005, including the D17A1, D17A2, D17A6, and D17A7 engine types, this gasket is suitable for both aluminum heads and cast iron blocks, providing versatility for various engine configurations. The multi-layer steel (MLS) construction enhances strength, elasticity, and corrosion resistance, making it ideal for high-output engines that require maximum sealing performance without sealants. The outer embossed layers are coated with Viton, a heat-resistant elastomer capable of withstanding temperatures up to 482°F, ensuring a resilient seal in extreme environments. The center or shim layer, made of uncoated stainless steel, can be customized to meet specific thickness requirements, offering flexibility for engine rebuilds or modifications. Perfect for enthusiasts and professionals seeking a high-quality replacement, this MLS gasket ensures a tight seal under shearing forces created by different materials and operating conditions. Its precise fit and durable materials make it a reliable choice for maintaining engine integrity and performance over time.
