Frequently Asked Questions (FAQ):

What is the purpose of an anti shudder valve?

It prevents a runaway diesel and also allows for a quieter engine shutdown.

Why do people remove the anti shudder valve completely and replace it with a "race pipe"?

Having an anti shudder valve can be restrictive on the intake, therefore once it has been removed you will notice increased power and better throttle response.

Can the anti shudder valve prevent my engine from starting?

Yes, it can stick closed which will not allow air into the engine.
