Description

The Seibon carbon fiber engine cover for the Toyota GR Corolla is designed to upgrade the engine bay with a lightweight carbon fiber component that enhances visual appeal while maintaining OEM-style fitment.

Replacing the factory engine cover with carbon fiber adds a motorsport-inspired look under the hood while subtly reducing weight compared to stock materials. Designed specifically for the GR Corolla platform, this engine cover integrates cleanly with factory mounting points and complements other carbon fiber components in the engine bay and exterior.

Available in both gloss and matte finishes, the Seibon engine cover allows you to tailor the engine bay aesthetic to match your build style—whether you prefer a high-gloss show finish or a stealth, performance-oriented appearance.

Finish Options

This product is available in two carbon fiber finishes:

Gloss Carbon Fiber

• Seibon SKU: EC23TYGRCOR

• High-gloss clear-coated carbon fiber finish

• Ideal for show-focused builds and matching exterior carbon fiber components

Matte Carbon Fiber

• Seibon SKU: EC23TYGRCOR-MF

• Satin/matte carbon fiber finish

• Ideal for track-inspired or understated engine bay builds

Both versions share the same construction, shape, and mounting points. The difference is purely visual.
