GReddy Type R BOV Stiff Spring

The GReddy Type R BOV Stiff Spring is a direct replacement for the spring that comes standard with the Type R blow-off valve. This stiffer spring is designed to help prevent premature valve opening under higher boost conditions. By using a stronger spring, you can ensure that your blow-off valve only actuates when it's supposed to, which helps maintain consistent boost pressure in turbocharged engines.

This spring is made from durable materials to withstand the rigors of a high-performance engine bay. It's a straightforward swap for the stock spring, making it an easy way to fine-tune your Type R blow-off valve's performance. If you're running increased boost levels or experiencing issues with your blow-off valve opening too soon, this stiffer spring can make a notable difference in how your turbo system behaves.
