2013–2020 Subaru BRZ / 2017–2020 Toyota 86 FA20D / 4U-GSE Engine
C4589-052
Overview:
The Cometic MLS (Multi-Layer Steel) head gasket for the left side is engineered specifically for the Subaru BRZ (2013–2020) and Toyota 86 (2017–2020) equipped with the FA20D and 4U-GSE engines. Designed to provide a reliable and durable seal between the cylinder head and engine block, this gasket ensures optimal engine performance and longevity. It is ideal for enthusiasts and professionals seeking a high-quality replacement or upgrade part that withstands demanding operating conditions.
Built to handle the stresses of both street and track use, this gasket maintains a tight seal under high pressure and temperature fluctuations, helping to prevent leaks and maintain engine efficiency.
Key Features:
Cometic’s head gasket incorporates advanced materials and design features to deliver superior sealing performance:
- Multi-layer steel construction with three to five layers for enhanced strength and durability
- Outer layers embossed and coated with heat-resistant Viton rubber for superior sealing and corrosion resistance
- Viton coating rated to withstand temperatures up to 250°C (482°F)
- Precision engineered for an 89.5mm bore size, matching factory specifications
- Designed specifically for the left-hand side (LHS) of the cylinder head
- Compatible with Subaru FA20D and Toyota 4U-GSE engines
- Thickness of .052 inches for optimal sealing and compression retention
- Resilient to harsh sealing environments, load conditions, and varying surface finishes
Construction & Design:
The Cometic MLS head gasket is constructed from multiple layers of stainless steel, chosen for its strength, flexibility, and corrosion resistance. This multi-layer design allows the gasket to rebound and maintain a consistent seal even under extreme thermal cycling and mechanical stress. The embossed outer layers increase sealing surface contact, while the Viton rubber coating on both sides enhances the gasket’s ability to resist oil, coolant, and combustion gases.
This combination of materials and engineering ensures a long-lasting, reliable seal that supports high-performance applications without compromising durability or engine integrity.
Installation & Fitment:
This gasket is a direct fit replacement for the left side cylinder head on Subaru BRZ models from 2013 through 2020 and Toyota 86 models from 2017 through 2020. Installation requires standard head gasket replacement procedures and should be performed by a qualified technician to ensure proper torque specifications and surface preparation. No modifications are necessary, as the gasket is designed to OEM dimensions and tolerances.

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
