GReddy Type R BOV Replacement Diaphragm

The GReddy Type R BOV Replacement Diaphragm is made from a durable silicone material. This diaphragm is the heart of your Type R blow-off valve, controlling when and how quickly it releases boost pressure. Over time, the original diaphragm can wear out or develop small tears, leading to boost leaks and a loss of performance. Replacing it with a fresh, well-made diaphragm from GReddy will restore your blow-off valve's proper operation.

This diaphragm is specifically designed to fit the GReddy Type R blow-off valve. Its precise dimensions ensure a tight seal, preventing any unwanted boost leaks that could rob your engine of power. A properly functioning blow-off valve is crucial for protecting your turbocharger from excessive pressure when you lift off the throttle. If you've noticed your Type R BOV isn't holding boost like it used to, or if you're hearing a hissing sound under boost, this replacement diaphragm is likely what you need.
