Cometic Gasket MLS Head Gasket
2005–2010 Scion tC / 2008–2014 Scion xB (xB2)
C4506-027
Overview:
The Cometic Gasket MLS (Multi-Layer Steel) Head Gasket is engineered to deliver superior sealing performance for high-output engines, specifically designed for the Scion tC (2005–2010) and Scion xB (2008–2014) models. Constructed from multiple embossed layers of stainless steel with Viton rubber-coated outer layers, this gasket ensures a reliable, durable seal without the need for additional sealants. Whether your vehicle is used for daily driving or spirited performance, this head gasket offers enhanced durability and resistance to corrosion and thermal stress.
Ideal for engines with aluminum heads paired to aluminum or cast iron blocks, the Cometic MLS Head Gasket withstands the shearing forces caused by differing metal expansion rates, maintaining a consistent seal under demanding conditions.
Key Features:
This head gasket incorporates advanced materials and design to provide a robust and long-lasting seal for your engine:
- Multi-layer stainless steel construction for increased strength and durability.
- Embossed outer layers coated with Viton rubber, a heat-resistant fluor elastomer rated up to 250°C (482°F), ensuring excellent sealing under high temperatures.
- Compressed operating thickness of 0.027 inches, optimized for precise fitment and sealing.
- Center shim layer of uncoated stainless steel, allowing for varied thickness to meet specific engine requirements.
- Designed to handle the shearing forces between aluminum heads and aluminum or cast iron blocks.
- Corrosion-resistant materials extend gasket life and maintain performance over time.
- No sealants required, simplifying installation and reducing the risk of leaks.
- Precision bore size of 92mm, matching Toyota 2AZ-FE and 2AZ-FXE engine specifications.
Construction & Design:
The Cometic MLS Head Gasket features a sophisticated multi-layer steel design that balances flexibility and strength. The embossed stainless steel layers provide a spring-like effect, allowing the gasket to rebound and maintain a tight seal despite thermal expansion and contraction cycles. The Viton coating on both sides of the outer layers enhances sealing capability by conforming to surface irregularities and resisting heat and chemical degradation.
This gasket’s design is particularly suited for the Toyota 2AZ-FE and 2AZ-FXE engines found in the Scion tC and xB, ensuring compatibility and reliable performance. The use of high-quality stainless steel and Viton materials guarantees resistance to corrosion and wear, critical for maintaining engine integrity over extended use.
Installation & Fitment:
The Cometic MLS Head Gasket is a direct replacement part engineered for a precise fit on the following vehicles:
- Scion tC Base 2005–2010
- Scion tC Spec 2007–2008
- Scion xB Base 2008–2014 (xB2)
Installation requires no additional sealants, and the gasket is designed to fit OEM specifications, ensuring a straightforward bolt-on replacement. No cutting, drilling, or special tuning is necessary, making it suitable for both professional mechanics and experienced DIY enthusiasts.
