Forge Valve Spring Tuning Kit

Product Details

Enhance your BMW’s performance by fine-tuning your diverter or blow-off valve with this kit that includes four springs of varying strengths. When the valve releases more pressure than necessary or when boost pressure is decreasing, it’s a sign that a stronger spring might be needed.

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
