2005-2010 Ford Mustang GT 4.6L V8 Exhaust Header Gasket

Seal your header-to-manifold joint with a replacement gasket engineered for the 4.6L V8. Factory gaskets fail from heat cycling and exhaust pressure, causing leaks and rough idle. This gasket restores the seal without requiring header removal on most installations.

Frequently Asked Questions

Do I need to remove the header to install this gasket?

Most 4.6L V8 builds allow gasket replacement without full header removal — you can access the joint from above the motor. Check your specific header design and available clearance before starting work.

What fasteners do I need to secure the gasket?

This gasket unit only; fasteners are not included. Your header bolts and any existing hardware will hold the gasket in place. Refer to your vehicle service manual for correct torque specs.

Can I reuse this gasket if I remove the header later?

No — header gaskets are crush-sealed and cannot be reused once removed. Plan on a fresh gasket every time you break the joint apart.

Products received may vary slightly from images due to manufacturing tolerances or supply chain variables.
