As we are all learning the weakest link in a high power GR Yaris is the valvetrain, we believe that a lot of engine failures are initially caused by valvetrain failure. 

Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines.

A cooler valve improves the material strength and durability.

For use in turbocharged hi stress engines
