Supertech VW 1.8L/2.0L 8V Black Nitrided Exhaust Valve - +1mm Oversize - Single Dia

This Supertech exhaust valve is treated with a black nitride finish, a surface hardening process that helps it resist wear and corrosion. It's designed for VW 1.8L and 2.0L 8-valve engines, and this particular valve is 1 millimeter larger than the stock size, often used when rebuilding or modifying cylinder heads to improve flow or compensate for wear.

The nitriding process creates a tough outer layer on the valve face and stem, which is beneficial for the high temperatures and stresses exhaust valves endure. Being a +1mm oversize valve means it will require a matching valve seat to be installed, ensuring a proper seal. This is a single valve, so you'll need to order the correct quantity for your engine's needs.
