Show original supplier description
The Tomei TA4070-TY07A is a multi-layer steel (MLS) head gasket specifically engineered for the Toyota G16E-GTS engine found in the GR Yaris and GR Corolla. This performance tuning part features an 89mm bore and a 0.6mm thickness, designed to improve sealing performance and durability for high-output builds. The G16E-GTS engine, known for its compact 1.6-liter displacement and turbocharger, achieves high power density but can be subjected to significantly higher loads when modified. This MLS head gasket utilizes a multi-layer stainless steel construction to balance sealing performance, load retention, and thermal adaptability. It incorporates a raised bead structure combined with a stopper-type sealing design around the cylinder bores to concentrate clamping force for stable sealing under extreme cylinder pressure and resist cylinder head lift. Beyond combustion sealing, the Tomei gasket precisely seals coolant and oil passages, reducing the risk of leaks and cross-contamination. The 0.6mm thickness of the TA4070-TY07A is ideal for stock turbo setups, mild tuning, street performance builds, and applications prioritizing fast throttle response, offering a slight increase in compression ratio. This head gasket is developed to provide confidence under load for demanding motorsport environments and performance tuning, ensuring reliability during extended high-load operation, track sessions, and competitive driving.
