This genuine GFB 9psi middle spring is a replacement for the EX50 external wastegate. It swaps directly for the factory middle spring, letting you adjust base boost pressure and fine-tune your boost curve without a full wastegate rebuild. It is a universal component rather than a vehicle-specific one and suits any application already running an EX50. Confirm your EX50 configuration and boost target before ordering.
