Supertech Toyota 2JZ Sodium Filled Inconel Exhaust Valve - +1mm Oversize - Single

This listing is for a single Supertech exhaust valve designed for the Toyota 2JZ engine. It's a +1mm oversize valve, meaning it's slightly larger than the stock diameter to potentially improve airflow into the cylinder. The valve itself is constructed from Inconel, a strong alloy known for its high-temperature resistance, making it suitable for demanding engine conditions.

The key feature here is the sodium-filled stem. This sodium core helps to dissipate heat away from the valve face and stem, keeping temperatures lower and reducing the risk of valve distortion or failure under extreme heat. This is a well-built component for those rebuilding or modifying a 2JZ engine where reliability and performance at higher temperatures are important.
