Optimize your BMW's performance by adjusting your diverter or blow-off valve using this kit containing four springs with varying strengths. When noticing excessive pressure release or a drop in boost pressure, it's an indicator that a stronger spring might be necessary.

Important Notes:

  • Fitting a stronger spring won't increase boost pressure unless there's a pressure loss.
  • Installing an excessively strong spring may damage the turbocharger if it restricts the valve's operation.

Valve Spring Color Coding:

  • Green: Suitable for 5-15 PSI
  • Yellow: Ideal for 15-23 PSI
  • Blue: Designed for 23-30 PSI
  • Red: Suitable for 30+ PSI
