Supertech Black Nitrided Exhaust Valve Set of 8 for Audi VW 1.8L 2.0L 1990-1997 - VWEVN-1034-8

If you're looking to give your Audi or Volkswagen a little extra oomph, these Black Nitrided Exhaust Valves from Supertech are worth checking out. I’ve been around the block with plenty of engine parts, and let me tell you, these valves are solid. Made with a black nitrided finish, they’re not just about looks; they’re built to withstand the heat and pressure of your engine while keeping things running smoothly.

This set comes with 8 valves, so you can replace all the exhaust valves in your engine without having to worry about mismatched parts. They’ve got a head diameter of 28.00mm, a stem diameter of 6.96mm, and a length of 98.20mm. So, whether you’re working on a 1.8L or a 2.0L engine, these valves are designed to fit like a glove in models like the Audi 90 Quattro and the Volkswagen Golf MK2, among others.

What I really like about these valves is their precision engineering. Supertech doesn’t cut corners, and you can expect these to hold up for years, giving you peace of mind as you push your car to its limits. Plus, they’ll help you get the most out of your engine, making sure that exhaust flow is optimized for better performance. It’s all about those little details that keep your ride feeling fresh.

So, if you’re driving an Audi 90 Quattro from 1990-1991, a Coupe Quattro from the same years, or a Volkswagen Golf or Jetta from the early '90s, these valves are a no-brainer. They fit right in, and you won't have to do any crazy modifications to make them work. Just swap them out and feel the difference.

In short, if you want to keep your classic VW or Audi running strong, these Black Nitrided Exhaust Valves are a smart choice. They’re tough, reliable, and designed to help your engine breathe better. Grab a set and see what they can do for your ride!
