  • Insert the K&N panel filter into the airbox.
  • Reattach the airbox cover securely.

Forge Diverter Valve

The Forge diverter valve is another essential upgrade for the Mk1 TT 1.8T. It replaces the factory diverter valve, which can become inefficient over time. The Forge valve offers several advantages:

  • Improved Boost Control: The Forge valve helps maintain boost pressure more effectively, leading to a more responsive throttle.
  • Durable Construction: Made from high-quality materials, the Forge valve is built to withstand higher pressures and temperatures.
  • Customizable: The valve can be adjusted to suit your driving style and performance needs.

  • Install the Forge diverter valve in the same position.
  • Reconnect the vacuum lines and electrical connector.

Performance Gains

After installing the K&N panel filter and the Forge diverter valve, drivers often report noticeable improvements in engine performance. The combination of increased airflow and better boost control can lead to:

  • Enhanced acceleration and throttle response.
  • Increased horsepower, often in the range of 10-20 additional horsepower.
  • Improved turbo spool time, resulting in quicker power delivery.
