Product Description

The Cometic C4311-040 MLS head gasket is engineered for Honda K-series engines, including the K20A2, K20A3, K24A1, K24A4, and K24Z1. This gasket is designed with a 87mm bore and a 0.040" (1.02mm) compressed thickness, making it suitable for both stock and mildly overbored applications. Its MLS construction, combined with Viton-coated outer layers, ensures superior sealing for high-performance and forced induction setups.

The three-layer design of this gasket minimizes bore distortion by requiring less clamp load, while also distributing load evenly across the sealing area. The Viton coating adds an extra layer of heat resistance, ensuring the gasket performs under high pressure and temperature conditions. It is an ideal choice for performance applications or engine builds requiring precise sealing and high durability. Additionally, no re-torque is needed after the initial torque set, simplifying installation and providing long-lasting reliability.
