Construction & Design

The Cometic MLS head gasket features a multi-layer steel construction that combines durability with excellent sealing properties. Each gasket is meticulously manufactured using CNC-machined sealing surfaces to ensure a precise fit on the Mitsubishi 4G63 engine family. The multi-layer design allows for better conformability to surface irregularities, providing a reliable seal even under high cylinder pressures.

The gasket's .027 inch thickness strikes a balance between maintaining proper compression ratios and accommodating slight surface imperfections, making it suitable for both stock rebuilds and performance modifications. Its heat-resistant steel layers help withstand the intense thermal cycles experienced during spirited driving and racing, reducing the risk of gasket failure.

Performance & Sound

While this gasket is primarily focused on sealing and durability, its high-quality construction ensures consistent engine performance. By maintaining proper compression and preventing leaks, it helps support increased horsepower and torque output. The MLS design also contributes to a more stable combustion process, which can translate into smoother operation and improved throttle response.
