C4507-098
Overview:
The Cometic MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to provide superior sealing performance for high-output engines, specifically designed for Scion tC models from 2005 to 2010 and Scion xB models from 2008 to 2012. This gasket is ideal for enthusiasts and mechanics seeking a reliable, durable solution that withstands the demanding conditions of modern engines without the need for additional sealants.
Built to handle the stresses between aluminum heads and both aluminum and cast iron blocks, the gasket ensures a secure seal that resists corrosion and shearing forces. Whether you are restoring, upgrading, or maintaining your vehicle, this gasket offers peace of mind with its advanced construction and materials.
Key Features:
This Cometic MLS head gasket incorporates advanced materials and design features to deliver lasting performance and reliability:
- Constructed from multiple embossed layers of stainless steel for enhanced strength and durability.
- Outer layers coated with Viton rubber, a heat-resistant fluor elastomer rated up to 250°C (482°F), providing excellent sealing under harsh conditions.
- Compressed operating thickness of 0.036 inches ensures a precise fit and optimal sealing.
- Designed to accommodate the shearing forces between aluminum heads and aluminum or cast iron blocks, preventing leaks and gasket failure.
- Center shim layer of uncoated stainless steel allows for thickness variation to meet specific engine requirements.
- Embossed outer layers improve gasket rebound and resistance to corrosion over time.
- Coated on both sides with Viton to maintain a secure seal across a variety of surface finishes and load conditions.
- Compatible with Toyota 2AZ-FE and 2AZ-FXE engines, featuring an 89mm bore size.
Construction & Design:
The Cometic MLS Cylinder Head Gasket utilizes a multi-layer steel design that combines strength and flexibility. The embossed stainless steel layers provide the gasket with the ability to rebound after compression, maintaining a tight seal even under extreme thermal and mechanical stress. The Viton coating on both sides enhances sealing capability and protects against chemical and heat degradation, making it suitable for high-performance and daily-driven engines alike.
This gasket’s design is optimized for use with aluminum cylinder heads and blocks, as well as aluminum heads paired with cast iron blocks, effectively managing the different expansion rates and shear forces between these materials. The precise thickness and layered construction ensure consistent sealing performance without the need for additional sealants.
Installation & Fitment:
This gasket is a direct replacement designed to fit the following vehicles and engine configurations without modification:
- Scion tC Base (2005–2010)
- Scion tC Spec (2007–2008)
- Scion xB Base (2008–2012)
It also fits a wide range of Toyota models equipped with the 2AZ-FE/2AZ-FXE engines, including various Camry, Corolla, Highlander, Matrix, RAV4, and Solara trims from the early 2000s through 2012. No cutting, drilling, or special tuning is required for installation, making it a straightforward upgrade or replacement for your vehicle’s cylinder head gasket.
