Product Details
If you're rebuilding the top end of your Toyota 4AGE 20V engine for improved performance, you'll want to pay close attention to the valves. This Supertech exhaust valve is designed as a +1mm oversize replacement, meaning it's slightly larger than stock to help improve flow and sealing in the combustion chamber.
The valve itself is black nitrided, a surface treatment that hardens the material and improves its resistance to wear and heat. This is especially important for exhaust valves, which endure high temperatures and exhaust gas flow. Being a single valve, it's perfect for replacing individual damaged or worn valves, or for custom builds where you might be mixing and matching components.
