GR Yaris & GR Corolla Billet Valve Cover
Engineered with precision. Designed to perform.
The Ichiban Engineering GR Yaris Billet Valve Cover is a premium upgrade for both the Toyota GR Yaris and GR Corolla, combining OEM-level fitment with motorsport-grade materials and functionality.
To achieve absolute accuracy, we began by 3D-scanning the actual engine and OEM valve cover, capturing every contour, mounting point, and sealing surface. The result is a billet valve cover that fits perfectly while improving strength, durability, and crankcase ventilation capability.
Machined from aerospace-grade 6061 aluminum, this valve cover offers exceptional rigidity and heat resistance compared to the factory unit. We retained all OEM mounting locations, ensuring that factory accessories and components bolt on exactly as intended — no compromises, no surprises.
For performance applications, the cover features two integrated ORB10 / AN10 breather ports, paired with special low-mounted banjo AN10 fittings. This design provides excellent clearance and clean routing for catch cans or external ventilation systems, even in tight engine bays.
Unlike many aftermarket options, we intentionally retain the OEM gasket design instead of using an O-ring. This ensures proven sealing reliability, consistent clamping force, and long-term leak-free operation using readily available OEM gaskets.
To finish it off, each GR Yaris Billet Valve Cover is available in a range of anodized color options, allowing you to match your engine bay while maintaining a factory-clean look.
