Supertech Black Nitrided Intake Valve Set of 4 for Volkswagen 1.8L 2.0L 8V Engines - VWIVN-1014-4

If you're looking to squeeze every bit of performance out of your engine, check out the Black Nitrided Intake Valves from Supertech. I’ve had my hands on these bad boys, and let me tell you, they’re a solid upgrade for anyone serious about their ride. Made with precision and care, these valves are designed to not just meet but exceed the high standards you’d expect in the industry.

Each set comes with four valves, perfect for a full replacement. The black nitrided finish isn’t just for looks; it enhances durability and helps reduce wear over time. I’ve seen these valves stand the test of time in various setups, giving you peace of mind that they’ll hold up for years to come. You really can feel the difference in throttle response and overall engine efficiency.

Now, let’s get into the specs because I know that’s what really matters. The head diameter is 40.00mm, which is standard for a lot of setups, while the stem diameter sits at 7.00mm. The length of each valve is 91.60mm, making them a perfect fit for a variety of Audi and Volkswagen models. Seriously, if you’re rocking a classic Audi 4000 or a Volkswagen Golf from any of the MK generations, these valves are going to fit right in.

Here’s a quick rundown of the vehicles that can benefit from these valves:

  • Audi 4000 (1985-1987)
  • Audi 80 (1988-1990)
  • Audi 90 (1988)
  • Volkswagen Beetle (1998-2003)
  • Volkswagen Cabriolet (1985-1993)
  • Volkswagen Corrado (1990-1992)
  • Volkswagen Eurovan (1997-1999)
  • Volkswagen Fox (1987-1993)
  • Volkswagen Golf (1985-2003)
  • Volkswagen Jetta (1985-2004)
  • Volkswagen Quantum (1984-1985)
  • Volkswagen Scirocco (1984-1988)

So if you’re ready to give your engine the upgrade it deserves, these Supertech Black Nitrided Intake Valves are a no-brainer. They’re built to last and designed to perform, making them a great addition to your performance parts arsenal.
