This MLS (Multi-Layer Steel) head gasket is crafted to withstand the rigors of high-performance applications, offering superior durability and sealing capabilities compared to traditional OEM gaskets. Its design helps prevent head gasket failure, oil leaks, and coolant leaks, ensuring your engine maintains optimal performance and reliability over time.

Key Features

Designed with performance and durability in mind, the Cometic MLS Head Gasket incorporates several innovative features:

• Constructed with multiple layers of high-quality stainless steel, providing exceptional strength and resilience to engine heat and pressure.
• Embossed outer layers enhance sealing surface contact and improve load distribution across the gasket.
• Coated on both sides with a fluoroealastomer rubber-based material (Viton), which offers excellent resistance to heat, chemicals, and harsh engine environments.
• Viton coating is heat resistant up to 250°C (482°F), ensuring reliable sealing even under high-temperature conditions.
• Engineered to meet or exceed OEM specifications, providing a perfect fit and seal for your engine rebuild or upgrade.
• Designed to rebound and maintain its shape under load, reducing the risk of gasket failure during high-performance operation.
• Corrosion-resistant materials extend the lifespan of the gasket, especially in demanding racing or tuning scenarios.
• Precision manufacturing and quality control ensure consistent thickness and surface finish, critical for proper sealing and compression.
• Compatible with a variety of Honda and Acura B-series engines, making it a versatile choice for engine builders and tuners.

Construction & Design

The Cometic MLS Head Gasket features a multi-layer steel construction, which provides superior strength and flexibility. The embossed outer layers are designed to improve sealing contact and load distribution, reducing the likelihood of leaks. The gasket's surface is coated with Viton, a fluoroealastomer rubber-based material, which enhances heat resistance and chemical stability. This combination of materials ensures the gasket can withstand the high temperatures and pressures typical of high-performance engines.

The gasket's precise manufacturing process guarantees uniform thickness and surface finish, critical for achieving a proper seal and maintaining engine compression. Its ability to rebound and recover shape under load helps prevent gasket blowouts, especially during aggressive driving or engine modifications. The stainless steel layers are corrosion-resistant, further extending the gasket's service life in demanding environments.

Performance & Sound

While this gasket is primarily designed for sealing and durability, its high-quality construction ensures consistent compression and sealing integrity, which contributes to optimal engine performance. Proper sealing helps maintain consistent compression ratios, supporting reliable power output and efficient combustion. The gasket's robust design minimizes the risk of leaks that could compromise engine performance or cause overheating.

Installation & Fitment

The Cometic MLS Head Gasket is a direct replacement for OEM head gaskets on compatible Honda and Acura B-series engines. Installation is straightforward for experienced mechanics and engine builders familiar with head gasket replacement procedures. It is recommended to follow the manufacturer’s torque specifications and tightening sequence to ensure proper sealing and prevent warping or damage.

No cutting, drilling, or special modifications are required for installation. Ensure the mating surfaces are clean and free of debris before installation to maximize sealing performance. Using new head bolts and following proper torque procedures will help achieve the best results.
