What is the main benefit of using a plumback adaptor?

A plumback adaptor allows your blow-off valve to recirculate the vented boost air back into the intake system. This helps maintain the engine's air-fuel ratio and significantly reduces the noise associated with venting boost to the atmosphere.

Will this adaptor fit any blow-off valve?

This adaptor is specifically designed to fit Go Fast Bits 38mm blow-off valves. It is not a universal fit and will not work with other brands or sizes of blow-off valves.

Can this adaptor be shipped to California?

No, this product is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This 38mm Plumback Adaptor from Go Fast Bits is designed to work with their blow-off valves, allowing you to recirculate the vented air back into the intake system. This setup is often preferred for street applications as it keeps the vented air quiet and prevents potential issues with the engine's air-fuel mixture that can occur when venting to atmosphere. The adaptor is made from durable materials to ensure it holds up under boost pressure.

By recirculating the boost, you help maintain the correct air-fuel ratio, which can lead to smoother engine operation. This adaptor is a straightforward way to modify your existing GFB blow-off valve setup for a quieter, more street-friendly performance. It's a well-built piece that fits right onto compatible GFB valves.
