Supertech BMW M20B25 Inconel Exhaust Valve - +1mm Oversize - Set of 6

This is a set of six Supertech Inconel exhaust valves, specifically designed for the BMW M20B25 engine. These valves are made to a +1mm oversize, which can be beneficial when rebuilding or upgrading your cylinder head to improve sealing and performance. Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme heat and corrosion, making it ideal for exhaust valve applications where temperatures can get very high.

Using Inconel for exhaust valves means they can better withstand the harsh conditions inside the combustion chamber, especially under sustained high-performance driving or in turbocharged applications. The +1mm oversize dimension is a common choice for performance builds, allowing for a larger valve face to potentially improve airflow into the cylinder and provide a fresh sealing surface if the original valve seats have wear. This set is a well-built option for enthusiasts looking to enhance the durability and performance of their M20B25 engine's valvetrain.
