Supertech Nissan SR20D Inconel Exhaust Valve - +1mm Oversize - Single (Drop Ship Only)

This is a Supertech Inconel exhaust valve designed for Nissan SR20D engines. It's a +1mm oversize valve, meaning it's slightly larger than the stock valve to help improve airflow into the cylinder. If you're rebuilding the top end of your SR20D, especially for a performance application, these valves are a solid choice.

Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures, making it ideal for exhaust valves that endure a lot of heat. This particular valve is 1mm larger than the factory specification, which can contribute to better cylinder filling and potentially improved performance. It's a single valve, so you'll need to order the correct quantity for your engine's needs.
