Supertech Mazda FS/Protege 2.0L Inconel Exhaust Valve - +2mm Oversize - Single

In this package, you get a single Supertech Inconel exhaust valve. This valve is designed to be 2mm larger than the stock size, which can help improve airflow into the cylinder. It's intended for use in Mazda FS and Protege 2.0L engines.

The valve is made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme heat. This makes it a solid choice for performance builds or engines that see a lot of hard use, where exhaust valve temperatures can get very high. The +2mm oversize design means it's a bit bigger than the original valve, which can contribute to better breathing for the engine. Keep in mind that when installing oversize valves, you'll need to ensure the valve seats in the cylinder head are properly machined to match the new valve's dimensions.
