Supertech Audi/VW 1.8T 5V Triple Groove Black Nitride Exhaust Valve - Set of 12

These Supertech exhaust valves feature a triple groove design, a detail that helps ensure proper valve spring retainer positioning. The valves themselves are treated with a black nitride finish, a process that hardens the surface and improves resistance to wear and corrosion. This is a set of 12, intended for the 1.8T 5-valve Audi and Volkswagen engines.

When you're rebuilding the top end of your 1.8T, using well-built valves like these can make a real difference. The black nitride treatment isn't just for looks; it adds a layer of toughness that helps these valves stand up to the heat and stress of combustion. This means they'll seal better for longer, contributing to consistent engine performance. The triple groove design is a nod to performance applications, offering a secure fit for the valve keepers.

If you're working on a 1.8T engine that needs new exhaust valves, this set from Supertech is a solid option. They're made to fit the specific 5-valve cylinder heads found on many Audi and VW models from the late 90s through the mid-2000s. Make sure you have the correct number of valves for your engine before ordering.
